I can confidently assert that EVERY SINGLE MASS SHOOTING that has ever been prevented in the history of prevented mass shootings was prevented by a citizen with an AR-15. Especially mass shootings that were prevented in gun shops, police stations and firing ranges.
Prove me wrong, DUMBFUCK.
And then tell me how many UNPREVENTED mass shootings took place in an area that was designated a gun free zone for the safety of its patrons.
DUMBFUCK gotta DUMBFUCK.
