you are confusing serious criminals with persons simple hoping to have a better life, or to make some decent money to go home and start a business, over there.
Spare me your sob-story buttercup. I could care less what their intentions are - they
broke U.S. law. That makes them a criminal.
Second - why do they need to come to the U.S. for (and I quote) "a better life"?
Third - if they want a "better life" they can build it in their own damn country. Don't run to the U.S. - dig your heels in and make Mexico better.
