And if one bothers to read the link, one of the reasons listed for exponentially increasing one's chances of being shot by the police is "running from the police".
Unarmed to most people means not having a weapon. In most cases, a weaponless person ought to be less than a threat to life to a police officer. "Looking like a threat" is not the same as "is an actual threat".
Fun Fact: the Massachusetts Supreme Judicial Court has ruled that some people who are innocent of wrongdoing have good reason to run from police, based on their long history of abuse and violence. And really nobody is arguing about someone that purposefully drives their car at a cop is being "peaceful" or even that said person is "unarmed". But then we get to people who are simply holding a toy gun in a Wal-Mart, that they pulled off a Wal-Mart shelf.
Or choke out a person who is being arrested for selling loose cigarettes, when they actually had just broken up a fight and were not selling loose cigarettes, and selling loose cigarettes wasn't an arrestable offense to begin with.
Or police that yank high-school kids off the busses they're on to go home, and then fire rubber bullets at them because they aren't going home.
Or who jump onto the hood of a car that had simply backfired, and fire until their gun runs out, and then reload, and repeat several times.
Or who knock down doors and pull naked women out into the public and handcuff them with no signs of any emergency.
Or who beat up bikini-clad teenagers in a rage.
Or who make excuses for racist wannabe vigilantes that chase down and murder teens that were simply walking home from the store.
Or who immediately begin driving around in military surplus, threatening an entire neighborhood with dogs and shotguns, and so forth, when the people are simply outside to mourn someone's death.
Or who drive up to a preteen with a toy gun and shoot him within 2 seconds of arrival.
Or, yes, who torture a guy with severe lead poisoning to death because he simply ran away from them.
So, basically, the article is bullshit.
