Is This Really Self Defence?

The first video that i can find. Is like, ok, here's a person admitting on camera that they shot somebody,. So now i can search for all those items together and the rest of the foodage collected throughout the night. Looking overthe top viral vidios of the night showing multiple people getting shot.
