I'm not saying it's any less dangerous, I'm saying the danger with operating heavy machinery isn't reduced by being ready to shoot someone if something goes wrong. In policework, it can be, hence more accidental shootings.How is it different than getting flattened by machinery or huge chunks of steel due to equipment failure or negligence of another employee, etc? If you're not on your toes the results aren't pretty, I've witnessed that first hand several times over the years. Just because the risk is "guns" it's a special case?
I'm too lazy to dig up links now, but any statistics I've ever seen put police well down the list of them risking their lives for their work. That's not to take away from what they do, but the old "they're putting their lives on the line" isn't special just because their job is protecting people. Bad people gonna be bad, that's the whole point of the police.
