People hopped up on drugs are so reasonable, aren't they. They don't resist arrest. He'd already been in jail for drugs and again for a weapons charge. Not a bright young man.
This guy was not executed. He was struggling and had a rap sheet. He was also hopped up on drugs which tends to make one uncooperative. He was with a gang terrorizing people on a train. He didn't want to go to jail again. The young men on either side of him complied with police orders. They are alive. Grant would be too but for the drugs in his system, fighting arrest and an accidental shooting.
I've read your posting history. You obviously have baggage and hate cops. You can't see the truth because of the baggage.
Have a good day.
