Thing is TZ, when you cross over a border illegally, you become a criminal. The majority of these people coming over are not "poor pathetic grape pickers", they are drug smugglers and hardened criminals, gang members, murderers.
Shooting them is not something I have a problem with, if they don't want to get their asses shot off, stay in Mexico or come through legal channels to get here.
I bet you, if we started shooting them, btw, shooting a tresspasser is legal in Texas, that they would stop coming here. Most people don't want to go where they know they're going to get pumped full of lead.
