ahh, but as we have advanced in technology we now use cars versus the ole horse to get us around from place to place. so, tell me, what happened to people who stole horses again? they were hung by the neck until dead if they were not shot in the act first. 

its a matter of perspective, a car which today can cost in excess of $30K is not a loaf of bread that costs $2. that's why our laws have different levels of criminality, a petty crime like the loaf of bread versus grand larceny like a vehicle, one is a misdemeanor the other is a felony. our police use deadly force all the time, why can't the citizen exercise the same? you don't think crime rates would go down if criminals knew there was a chance that people may defend themselves with deadly force if necessary?
