+1 I think there has been a concerted effort to persuade 'civilians' that being a cop is the equivalent of being in the military in terms of danger. Any level of response is justifiable when your life is 'continuously under threat.' What you see on TV is not representative of the average police officers daily life.
I just parsed the 2016 statistics from the Bureau of Labor Statistics (BLS):(https://www.bls.gov/iif/oshcfoi1.htm) and figured out that the fatal injury rate for 'Police and Sheriff's Patrol Officers' is 14.6 (the rate is a bit complicated, but weighted by total hours worked by total employees in that profession, to make jobs comparable)
Police work: @14.6 - slightly less, but roughly equivalently dangerous to Cement Manufacturing, Construction Laboring, working in Fish-Farming, Landscaping.
Professions that are 50%+ more likely to kill you than police work: Farming/Ranching (23.1), truck driving (24.7), steel-working (25.1), refuse collection (34.1)
More than THREE TIMES as dangerous as being a police officer: Roofing (48.6) and Aircraft pilots (55.5) (presumably a lot of private pilots crash?).
The most dangerous jobs in America today? Being a commercial fisherman (nearly six times as dangerous as being a cop) and Forestry Logging (more than NINE times more dangerous).
In case you're thinking it's a sample-size thing: in 2016, (according to the BLS), 108 police officers were fatally injured doing their job. 101 roofers, 91 loggers, 570(!) truck drivers.
So let's take truck driving, a considerably more dangerous profession than being a police officer, as an example. By the way, you 'need' truck drivers - it's how the food gets to your supermarkets and the medicines to the hospital. Truck driving, unhappily, causes some 'civilian' deaths, for a bunch of reasons: job stress, some bad training, some drivers don't take the mandatory breaks, maybe some use stimulants, whatever. How about we all look the other way when that happens, because, hey, it's a dangerous job, man? A lot of those truck drivers die on the job, y'know: you'd have to be one to understand.
I believe we should hold police to a higher standard than truck drivers, not a lower one. Being in danger is no excuse at all for being sloppy.
