They will think twice about trying to come back in again.
I hear Mexico does not tolerate illegal aliens on its southern border.
When will the U.S. stop being played for suckers?
Finally, I should take note of this point. If illegal aliens from Mexico were conservative and voted mostly Republican, the Democrats under Obama would have had a wall 100 feet high and 25 feet thick from San Ysidro to Brownsville, Texas.
I like it but I'd go farther: a 2nd capture-10 years in prison and then deportation. 3rd time-life in prison.
