A weapon gets an attacker more years in prison. A large group does not need weapons, but is still deadly. Plus, they feel secure that people won't shoot "unarmed teens".
if a mob attacks you, under disparity of force, you can use greater force to defend yourself.
if you are elderly, injured, disabled, smaller, weaker, or surprise attacked,
under disparity of force, you can use greater force than your attackers.
please remember this as it is a point of law.
And when a white individual gets attacked, who just so happens to be carrying, and starts shooting the attack gang of blacks, what do you think the Feds and media will do?
That would be a very BAD assumption if they were to attack me or my family!
