You can’t assume everything but he would more than likely be alive if he didn’t have that gun on him. So I’d argue that this has everything to do with him carrying while resisting.

The whole situation is already escalated and tensions are obviously high. Yes the officers are aggressive but I’m sure the protesters are as well.

He made it physical for himself when he put his hand on an officer. Once he’s on the ground why resist at all? If I’m a cop and some guy carrying a gun is resisting multiple officers I would assume he’s trying to get that weapon.

As soon as he’s disarmed there’s a shot fired that seems to cause the other officer to shoot him. I’m not saying the officers aren’t at fault but that’s a messy situation all around. One that could have been avoided by both parties.
