At a family Christmas party last night, I discussed this shooting with two family members...who happen to be Chicago cops. Both felt that this fatal shooting was JUSTIFIED! Upon further prodding, I discovered that:
1.) No matter what...the police officer's commands must be followed to the letter, no matter how "illogical" they may sound.
2.) Even when the suspect is scared to death because several cops are shouting threats and menacingly pointing their weapons at him, he should never make even the slightest "false move"...no matter how frightened he is. Any "false move" can get you shot.
3.) NO...it isn't enough for the suspect to remain face-down with his fingers interlocked behind his head. If the "peace officer" orders him to crawl forward while keeping his legs crossed...he is obligated to follow the officer's orders.
Those are the rules...like them or not.
