Journal: Magnetic Cell Phone Docks 6

Journal by chill

Just a short note. I picked up an Air Dock back when their Indigogo campaign was under way. I have now had this thing for a little over a year.

In general it works fine and does exactly what it says. I use the CD-mount, which has a nice picture down on this page.

The one flaw with that mount is the bolt and nut used to tighten it are fairly large, and extend beneath the mount. On DIN I sized radios, with the CD slot on top of the unit, the nut blocks the view of the display.

The one other thing I have discovered is that after a year of use, it has magnetized my phone! The Nexus 5 comes with small metal plates built in to the back to allow for the native use of devices like this. After all this time they have become magnetized, and that totally screws up the internal compass.

Now any time I start the compass app it complains the magnetic field strength is way too strong and it doesn't give accurate readings.

To be clear, this happens when the device is undocked and I'm walking around.

My next dock will be non-magnetic, as I do sometimes use the compass.

Journal: Reason 431 that I don't bother with Slashdot any more - 5 minute comment timer.

Journal by JWSmythe

I can type at over 100wpm. Slashdot's comment timer was set to 5 minutes a few years back. So if there is a particularly interesting article with interesting comments, I can comment and reply every 5 minutes.

If I'm going at 100wpm, I could write a 500 word essay as a comment. Or what happens more frequently is, I type out a nice constructive reply to someone, and am granted the text telling me I'm going too fast.

So I close the window and go elsewhere.

5 minutes between messages on a good conversation isn't conversing. I had FidoNet conversations go faster than that. I could type up and send faxes faster than that. With a bit of practice, I could send messages over short wave radio in morse code faster than that.

Even if my comment were "you sir are a moron", that leaves well over 4 minutes waiting for the timer to run out.

If anyone wants to have an intellectual conversation with me on an old Slashdot topic (like, appropriate for the genre "News For Nerds. Stuff That Matters"), find me elsewhere. Even this comment, would still have a 3 minute timeout before I could post it.

Journal: How Dangerous is Being a Cop in the US? 15

Journal by Jeremiah Cornelius
How Dangerous is Being a Cop in the US?

I saw a posting on Facebook (which I can no longer find, because Facebook posts are ephemeral and the algorithm used to put things on your timeline is apparently unstable) talking about the cost/person of police departments in major cities throughout the US. In the comments was the question "how much do you pay someone to risk getting shot every day?" with the implication that your average police officer in the US faces a substantial risk of death by gunfire daily, and therefore whatever the costs were, they were a good value.

And that got me thinking. Always a dangerous place for me to go.

How dangerous is it to be a police officer in the US? Is there significant risk of dying by gunfire? How does it compare with other occupations?

So let's go.


How many police officers are there in the US? How is that number changing annually?
According to the Bureau of Labor Statistics, there were 780,000 "Police and Detectives" in the US in 2012. That's our baseline. That number, BTW, is expected to grow by 5% by 2022, totaling about 821,000 by then. I'd love more data about this, but it's all I could find in a quick search, so we'll consider 780K as our baseline number of police in the US.


How many police officers died in the line of duty in 2012? Was that number "typical" for the years around it?
According to the National Law Enforcement Officers Memorial Fund, 122 officers died in the line of duty in 2012. That number is low compared to 2010 (161) and 2011 (171), but high compared to 2013 (100), so let's dig a little deeper with a graph:

Police Deaths by Year 1990-2013

Graph by Evan Robinson

Frankly, I think I see a slight downward trend in the data, but the math says otherwise. There's virtually no correlation between passage of time and number of police deaths. I note that 2001 (241) is quite an outlier. You have to go back to 1981 to get another year where more than 200 police died, but in the 70s, only 1977 (192) had fewer than 200 police deaths. The 70s were far worse than the 60s, which were worse than the 50s.


What's the chance of death in the line of duty for a police officer in the US? What's the chance of death by gunfire?
If there are 780,000 police officers in the US and 159.4 die annually (the mean from 1990 and 2013 inclusive), the chance of dying is 159.4 in 780,000 or 1 in 4892.8 or .0002. That's about 2 hundredths of a percent. Specifically taking 2012 numbers, it's 122 in 780,000 or 1 in 6393 or .00016, or about 16 thousandths of a percent. But let's take the higher number of 1 in about 4890, again .0002. Expressed as a death rate per 100,000, that is 20.4 -- that is, 20.4 of every 100,000 police officers in the US die annually from line-of-duty causes.

The overall annual death rate in the US for 2010 (the most recent final value I can find according to the Department of Health and Human Services, at the CDC website) was 747.0, with a preliminary value of 740.6 for 2011. So police line-of-duty death rates are about 3% of total mean death rates.

Police line-of-duty deaths, while tragic, are not a significant risk compared to mean death rates in the US.

But wait, we want to talk about gun-related police deaths, right? Again according to the National Law Enforcement Officers Memorial Fund, in 2012 50/122 officers killed died from gunfire. Over the past decade, the mean percentage of officer deaths from gunfire was 36%. So the gun-related death rate is 20.4*.36 = 7.4 per 100,000.


How do these death rates compare with other ages, causes, and professions?
In 2008 (the most recent year for which data in a complete Statistical Abstract of the United States is available), the only age range to have a death rate anywhere near that low is 5-14, where the male death rate was 24 and the female death rate was 12. Police officer line-of-duty deaths are therefore less common (statistically) than any death of 5-14 year old boys, although more common than 5-14 year old girls. Line-of-duty gun deaths are about one-third as common as all deaths of 5-14 year old boys and about half as common as all deaths of 5-14 year old girls. In 2008, the mean death rate for males 25-35 (in which age range I imagine many police officers fall) was 225. For males 35-44 it was 348. So depending upon their age range, police officers are between 10x and 17x more likely to die from non-work-related causes than line-of-duty causes. And 30x to 47x more likely to die from non-work-related causes than line-of-duty gunfire.

In 2006, comparable causes of death to all line-of-duty deaths include: Heart Failure (excluding ischemic heart disease aka "a heart attack") at 20.2; NonTransport Accidents (including falls, drowning, smoke inhalation, fire/flames, and poisoning) at 24.4; Diabetes at 24.2; Alzheimer's disease at 24.2; Drug and Alcohol induced deaths (combined) at 20.2.

Also in 2006, comparable causes of death to gun-related line-of-duty deaths include: prostate cancer at 9.5; Leukemia at 7.3; Falls at 7.0; Alcohol induced deaths at 7.4.

According to preliminary data for 2013 (see page 14), the rate of "fatal occupational injuries" in Construction is 9.4 per 100,000; Transportation and Warehousing is 13.1; Agriculture, forestry, fishing, and hunting is 22.2; Mining, quarrying, and oil and gas extraction is 12.3.

In other words, it's as dangerous to be a police officer as it is to be a farmer (3 million people), forester or logger (1.7 million people), commercial fisherman (1 million people) or hunter (about 14,000 people). So there are over 5.7 million jobs in the US more dangerous than being a police officer. And another 6 million in construction, which has a higher death rate than police gun-related deaths.


What's it all mean?
So yeah, being a police officer is a dangerous job, but the job-related danger is much less than your basic life-related danger (health problems, general accidents, etc.). And there are about 7 times more people doing Ag-related jobs which are more dangerous than being a police officer.

So what do we have to pay these people to risk being shot every day? I'd say a mean of about $57K per year, which is what they get. Maybe we need to raise the pay of the people in Agriculture, forestry, fishing, and hunting, who get mean annual wages in the $18K - $41K range for more dangerous jobs.


TL;DR (Too Long; Didn't Read)
I realize that putting the TL;DR way down here kind of defeats the purpose, but it allows me to put the conclusion after the work, which I like.

Being a police officer is a dangerous occupation. But there are plenty of people in the US who do more dangerous jobs for far less pay. Police line of duty death rates are comparable to death rates from Diabetes and Alzheimer's disease or the combination of drug and alcohol induced deaths. Police line of duty shooting death rates are comparable to alcohol induced deaths, Leukemia, or death by falling. A male police officer between 25 and 44 is many times (10x - 17x) more likely to die from a non-work-related cause than to die in the line of duty. And only about one-third of those line-of-duty deaths are gun-related.

And here's something else to think about
On average a police officer dies in the line of duty in the US about every 55 hours (everything you need for this calculation is above so I'm not going to insult your intelligence by including it). On average a police officer kills a civilian (about 400 annually) about every 22 hours. So I think we have more to worry about from them than they do from us.

As Yuval Harari points out, "What is so special about us that allows for such cooperation? Unflatteringly, it is our talent for deluding ourselves. If you examine any large-scale human cooperation (or co-option), you will always find some imaginary story at its base. As long as many people believe in the same stories about gods, nations, money or human rights (memes and antitropes) - they follow the same laws and rules (of conduct)."

"This is a vision of the world in which might makes right - a world in which one nation's borders can be redrawn by another, and civilized people are not allowed to recover the remains of their loved ones because of the truth that might be revealed. America stands for something different. We believe that right makes might - that bigger nations should not be able to bully smaller ones; that people should be able to choose their own future...

America is and will continue to be a Pacific power, promoting peace, stability, and the free flow of commerce among nations. But we will insist that all nations abide by the rules of the road, and resolve their territorial disputes peacefully, consistent with international law. That's how the Asia-Pacific has grown. And that's the only way to protect this progress going forward."
