So you propose sending them back, so they can break in again?
If you lock them up, just for breaking and entering illegally into the US (as opposed to giving them government services), I think you'd find illegal immigration dropping rapidly.
Then we seize the assets of anyone employing illegal aliens and auction everything off to cover the U.S. Taxpayer's cost of enforcement.
Let someone that knows how to run a business legally, without hiring illegal aliens, buy one that we confiscated from these un-American, criminal traitors.
Cut off their jobs, access to welfare, food stamps, all other social programs, education for their children, housing assistance and health care and the majority of these illegal aliens will DEPORT THEMSELVES and they won't come back! Why would they?
Use the money we save, by not supporting these deadbeats and incarcerating them, to build walls along our borders with Canada and Mexico to keep out those that are only coming here to commit crimes.
A president that had a spine could do it.
