Tell em 'take it up with the Dalhi Lama or Ghandi'
"If someone has a gun and is trying to kill you, it would be reasonable to shoot back with your own gun." Dali Lama
"Among the many misdeeds of the British rule in India, history will look upon the act of depriving a whole nation of arms, as the blackest."-Ghandi
Regarding cops having speical training, I go for an argument along the lines of 'okay, so you have 2 people, 2 women lets say whose estranged husband has threatened to kill them and they want Concealed Carry permits, are you really okay with a situation where 1 goes through training, the same training as a police officer, and takes the shooting test, gets 85, a passing grade, but the other person only gets an 84, and doesn't get to carry a gun? Do you really think that 1 point on some test is going to matter when like too many other battered women who finally leave, the husband finds her and beats her hard enough to kill her?
Now, I can throw out 'so it is okay for police because hey, they are police! just like Latoya Jackson and a whole slew of other C level celebs on reality tv'
