Did you read the article? The alleged criminal had sickle cell anemia but did not die from complications of that. The officers neglected to log that medical issue and did not allow him to get his medication for anemia.
I dug a little bit more for you Hacksaw. The guy was pulled over at 7:45 in the morning. He had been partying all night in a different city and hadn't slept as he and his friend drove to Montreal after partying all night long. His cause of death was heart failure due to cocaine in his system. He was 23 and already had two outstanding warrants. I couldn't find it what those were for, only that they were not related to weapons.
I'm firmly of the belief that acab. Well, 90% of them anyways. This dude, while not dangerous, was also not an upstanding citizen. He died from his poor choices.
I hope you learn to get as much info as you can before you go blasting people online. For the record, I volunteered in loss and bereavement for 8 years. "Passed" is a preferred term for the deceased.
