The supposed danger of police officers in America to gunfire because "AMERICA HAS SO MANY GUNZ" is actually completely incorrect. In 2013, only 105 police officers died in the line of duty out of an estimated 461,000+ sworn officers (likely more, as that count is from 2008, but we'll use that number for lack of anything better). This means that 0.022% of all police officers in the United States (again, at worst) were killed in the line of duty through any means. This includes accidents, their own negligence, heart attacks, and even one who died of illness related to 9/11.
For gunfire, 30 officers were shot to death by suspects (another 2 whom I won't count were killed accidentally, one from friendly fire and one from being a moron and shooting himself in the leg taking his guns out of his car). That gives us 0.00650% of all officers shot. They're already at less than a tenth of a percent chance of dying during their service each year, but the chance of a police officer in the United States being killed by another man's gun is so infinitesimally small that they are literally more likely to die driving to the scene of a crime than being shot at the crime scene.
To give a comparison, people have attempted to figure out how many deaths by police occur in the US. It's very difficult, as only about 750 of the 17,000+ agencies in the US actually contribute data. But a current count of just what we know is at least 1100 per year. Even with incomplete data, that's a 3566.6666% increase over how many civilians kill cops. Another entry made by the FBI in 2012 found approximately 400 "justifiable homicides" were committed each year by the less than 1000 agencies that provided data.
It's common for outside observers from other countries to try and treat the United States as essentially a warzone, where the police resort to deadly force so often because the criminals are packing heat and civilians are twitchy and armed. But looking at the actual statistics on who's killing who, you have to ask: exactly who's the biggest threat to your life in America?
The cops. When you hire brutish thugs, give them access to military-grade weapons, and give them a clear "us vs them" mentality, you're going to have a LOT of "justifiable" homicides;
especially when you're in a culture that practically idolizes your profession, is well-known for quickly, viciously blaming the victim, and does great fuck all when it comes down to cops who gun people down.
Yes, not all officers are thugs, but a great number of them are, and they're afforded a great deal of protection and are basically set above regular civilians. Laws don't mean dick if you aren't going to enforce them evenly, which is why the American justice system is likely seen as a complete, utter farce. On one hand, you've got rich civilians who could get out of brutally murdering someone simply because they're famous and can buy the best lawyers, and on the other, you've got a cadre of people in a caste just below the military, with half the training and discipline of said
actual soldiers, with almost every conventional weapon outside god damned stealth bombers at their disposal, who can and will get away with basically executing anyone that so much as looks at 'em funny, double points if they're a scary minority.
Maybe, if we adopted a more Swedish attitude, people like Michael Brown would still be alive, or if nothing else, his murderer would actually be behind bars with the rest of the violent psychopaths. As it stands, though, American "justice" is a fucking joke.
