we actually can count the examples.
in 2015 of 983 fatal shootings, 36 were on unarmed black men
https://www.washingtonpost.com/graphics ... shootings/that's 3.6% of all police shootings.
Of those, you can look at information about them on the site i put there...
8 had mental issues like schizophrenia and did things like attacked officers, 8 others attacked officers, 6 were from car chases, 2 tried to disarm officers, 1 reached for waistband, 1 reached into car, 1 was high on hallucinogens, and 1 "acted as if was armed". of the remaining 8 (0.8% of all shootings) there is some various causes for pause, although i'm not sure they all are real issues or not, just need more info. 1 was shot on street during warrant arrest. 1 was shot during robbery (confronted as he was leaving store). 1 was inadvertently shot by an officer when he went to taze him (oopsie!!!). 1 man was shot climbing into a hotel room (there was a call about a woman screaming and crying at the hotel). 1 was a bystander. 1 mistook cellphone for weapon. and 1 was the issue where some people say he was handcuffed but i don't think he was.
