I don't know why people are scared of the police. The vast majority of them are good people just doing their job trying to keep you safe. People's opinions of them are colored by ubiquitous news stories of the tiny fraction of bad cops, and their depiction in popular media. I was a passenger in a friends car when a police car pulled up next to us at a red light. I looked over, the cop looked over, I gave a friendly wave, he waved back. My friend went ballistic. "Are you trying to get me a ticket?"
I asked "Why? Are you doing something wrong?"
"Then what's your f#@$king problem?"
I've gotten several speeding tickets in my life; been involved in several accidents (not related to speeding and not my fault), and I've never had a negative experience with a police officer... when they ask to see my license and registration, instead of arguing with them, I hand it over. I was speeding, they pull me over, I know I was speeding... I've never seen cop give anyone a hard time unless they started arguing about it.
Does it happen that there are bad cops? Of course... but they're in the distinct minority. With all these cop haters on slashdot, you can be guaranteed they're happy enough a cop is around when they need one.
I don't know if it's required, but I believe they routinely do. My GPS consistently shows a few more MPH than my speedometer, and when I've taken long trips I've never gone as far as my speedometer told me I should have gone (based on MPH reported by my speedometer and keeping an eye on mile markers).
Back to the topic at hand, though, locations of police spotted in public locations is public information. This is the type of information that "wants to be free." My father was a police officer, I have several relatives who are still police officers, Several friends of my family are police officers... I highly respect them and, IMO, understand their point of view better than your average person. After seeing all the people lying, resisting, spitting in faces of police officers... I think that they have a LOT more restraint than most people are capable of. While it bothers me that police officers break, it's hardly surprising when the average person hates and distrusts them, despite the fact that 99% of the time they are good people doing their job... it's that tiny fraction that doesn't that makes the news, and colors people's perspectives.
I use waze... and I'll thumb up police reports if I see them, but I never slow down - because I'm not speeding to an extent where the cop would care. Around here the police on the interstates have a detrimental effect on commuter traffic, because when people see cops they slow down to 5 to 10 MPH below the limit, and it pisses me off. I cruise by police doing 5MPH over the limit and have never gotten a ticket. The very rare cases I've heard of people getting tickets for less than 5MPH over the limit have all been dismissed by the court. One department around here (at least) is ordered not to bother anybody doing less than 10MPH over the limit.
I give no credence to this complaint. I know that, in some locations, the police even use waze to see where they're being reported. Then they can move, they can "not there" the report - being a voluntary app (that I've only submitted information for twice because, hey, I'm driving here!) I find most of the reports dubious at best, and most of the time don't even see the cops that are supposed to be there.
The benefits of Waze over something like google maps is not the cop reporting - it's the accident and slow traffic reporting, it's the combined information from 100s or 1000s of "wazers" to help guide you around problem areas. The last time waze told me to detour and I didn't, I got stuck in an hour and a half of traffic I could have avoided.... never again.
The scientific community has Kevin Warwick to do that for you.
Like, I was over in England. You ever been to England, anyone, been to England? No one has handguns in England, not even the cops. True or false? True. Now-in England last year, they had fourteen deaths from handguns. FFFFFourteen. Now-the United States, and I think you know how we feel about handguns-woooo, I'm getting a warm tingly feeling just saying the fucking word, to be honest with you. I swear to you, I am hard. Twenty-three thousand deaths from handguns. Now let's go through those numbers again, because they're a little baffling at first glance. England, where no one has guns, fffffffourteen deaths. United States, and I think you know how we feel about guns-woooo, I'm getting a stiffy-twenty-three thousand deaths from handguns. But there's no connection, and you'd be a fool and a Communist to make one. There's no connection between having a gun and shooting someone with it, and not having a gun and not shooting someone. There have been studies made and there is no connection at all there. Yes. That's absolute proof. You know, fourteen deaths from handguns. Probably American tourists, too.
