Given proper military training...
... it might be possible, but...
.. you willin' to be the first to go unarmed...
... up against an AR-15?
If the crowd collapses on the shooter, the few hurried shots he gets off will be less accurate and he can't protect his back and flanks, I'm not saying single individuals should try to take them head on. If 40 rushed him at the same time from all angles he would be down in seconds. If you run, you just give them a clear field of fire where they can take time to aim.
Dear
OKTexas
From your point and responses, it seems it would take training in self-defense as well as group defense.
Not a bad idea. if we all had this training AND PEOPLE KNEW IT
then that might add to the deterrent effect as knowing people carry guns.
In Texas people know that citizens carry their own guns so they only go after targets they can isolate and get around that.
Now, you train EVERYONE in police and military tactics, and maybe that will increase deterrence.
People would try to avoid the same traps that military and police have to watch out for.
it could help with awareness and prevention on multiple levels.
Good suggestion, we should add this to community relations and police training,
and public school outreach to make sure people know how to defend themselves and work with authorities.
