I don't carry weapons, but you do realize that carrying weapons is not a reason to kill someone, yes?

In fact, people shouldn't be killed regardless. Police departments should really be out in front of this thing.

Police are justified in using deadly force any time they have reasonable cause to believe someone is putting their life in danger.

Resisting arrest, while carrying a gun, poses a very high risk of creating the perception among the arresting police officer and the officer shooting and killing you.
