No be there.Things I picked up on most in OP video.
The person shot was aiming for suicide by cop ala premeditation. This also involved the 9th circus...
Depending on locals and other conditions how do you effectively "train" to not be prosecuted by the ire of the courts which have shown to be very anti 2A?
You can train with weapons/tactics but how does one train against courts? Taking into account the above about the bad actions of the perp it seems like this was being used to weaponize a case against guns in general.
