Is it legal to shoot kidnappers who tries to abduct your children?


The recent arrest of pedophile kidnapping couple who abducted Caycee girl at the age of 11. She had been held in prison at the couple back yard.

I am wondering if you see the kidnappers doing their deeds, is it legal to shoot them to save the kids?

does any Canadian on this site know about Canadian law about this issue?
