I don't know enough about this particular event to have a full opinion, the initial video did not show the whole story, the second video doesn't tell the whole story. Apparently, Alton flashed a gun and threatened a homeless man, police were called and Alton was armed. Alton resisted arrest and while wrestling with him still resisting, Alton reached for the concealed firearm and was subsequently shot dead. I watched both videos, Alton was clearly not cooperating and although he was on his back both officers (not small men by any standard) were struggling to get him rolled over and cuffed and Alton was not having any part of it. Now perhaps the officers were far to aggressive at first but the call they had was a man with a gun who had threatened someone else already. They were on high alert, they don't know Alton all they know there is this armed guy that is a threat. Not to mention that Alton was a very large guy. Was it murder? No it's not like they walked up to him pulled a gun and shot him in the head. That's murder. They tried to make an arrest and the suspect got violent and resisted.
All Alton had to do was kneel and put his hands on his head and keep his mouth shut. Tell the officers he is indeed armed and where the firearm is located. Allow the officers to cuff him and remove the firearm for the officers own safety. If Alton is a legal concealed carry permit holder he would know these things. Now, brandishing a firearm in public is indeed illegal just about everywhere it is a threat of deadly intent and he probably would have been arrested and jailed and he would likely have lost his firearm and his permit. If he was not a licensed gun permit holder he would have been jailed and charged with a much more serious crime. Root cause of Alton's death? Do not fight with the police, just don't do it. Especially when armed. This one sways in favor of the officers.
The other recent shooting in Minneapolis was due to a frightened officer who panic'd. That was a truly tragic event, it never should have happened. The car was pulled over for a broken tail light. The driver was asked to produce his license and registration which is standard procedure. He correctly informed the officer that he was a concealed carry permit holder and he was armed. At this point the officer drew his weapon, again, standard operating procedure. What happened next is the bad part. The victim was complying but there was some form of communication breakdown and he reached to get his wallet and the officer shot him four times. This all took place in mere seconds. You never ever take your hands off the steering wheel and do not make any sudden movements! Wait for instructions and move slowly when ordered to move. Do not move till ordered to move. Be calm and clear. In this situation a police officer will want to cuff you and search you and the officer will then be the one to remove your weapon from your person. You certainly do not want the officer thinking you are reaching for the gun, no not ever.
You can hear the officer swearing repeatedly after the shooting throughout the video, he didn't want to shoot the guy. The officer knows he screwed up. At the same time the victim did in fact reach for his wallet where the gun could have been holstered. Truly tragic. The poor girlfriend had to watch him in pain, bleed out and die. Horrific. She was right her boyfriend didn't need to be shot dead.
The officer failed to properly manage the situation. As soon as he was told the driver was armed he went into an instant frightened mental state. He's likely never had to draw his weapon before let alone shoot someone. First words out of his mouth should have been, place your hands on the steering wheel and do not move. Freeze. Next words would be calmly explaining what happens next. "Sir, I want you to remain perfectly still. I need to secure your firearm and we are going to do this nice and slow. Do not move till I tell you to move. I will be cuffing you for both our protection and removing your firearm you are not under arrest. Do you understand? Please place your right hand outside the drivers window (attach first cuff), give me your left hand. Officer opens door with suspects hands engaged and has him step out slowly. Next step is to cuff both hands behind his back and lay down face first on the ground. Then he can ask where the firearm is located or just pat him down and remove it. Then unload it ensuring the chamber is clear. Help the suspect upright and seat him on the car bumper. Collect the ID/registration/gun permit and take the firearm back to the police car to check everything out. If everything was in good order, he can have a talk with the driver and just for a broken tail light give him a verbal or written warning. Now the passenger and child were in the car, he could have called for backup to assist in securing everyone carefully. There was absolutely no reason for this to have gone the way it did. It was a tragic accident and that officer is in pretty big trouble. If the driver really did reach for his waistband then the driver made a serious error. At the same time he's a civilian he's clueless about the police training. He was polite and cooperative but that one little movement and a frightened cop resulted in his death. Is it murder? No but it's absolutely terrible.
Police need better training that is for sure. They need to learn how to diffuse a situation and not escalate it. They need to know that black men are rightly angry and they need to find some way to calm things down. You don't rush in and abuse your authority right off the bat. You approach slowly and talk calmly. You tell them what you are doing and why. Howdy, seems we had a call in the area about a man with a gun. My partner over there is going to draw his weapon but that's just a precaution. Are you armed sir? You are not under arrest, I just need to secure the weapon and then we can talk about what happened. Please do not resist, stay calm. I do need to cuff you as a precaution, again you are not under arrest. Kneel down on the ground and put your hands on your head. Cuff him and that's it. Now if the guy suddenly gets agitated and mouthing off and waving his hands that's a very big problem. It's about respect not about an officers authority.
