"How would you know who to shoot 240. "
I'm glad you asked, 333386.
Our govt would pay $100 for each illegal worker reported. These employers would be fined out the ass. Our Army would be tightening up the border to ensure no more come in, while the 'demand' for them drops significantly as INS raids buffets, construciton sites and tomato fields.
Once the border is closed and those who are here can't find work for shit... they'll go home. I won't have to shoot anyone because the problem would have been solved with economic common sense
