mass incarcerations and deportations for mostly non-criminals (being in the U.S. w/o permission is a civil, not criminal, infraction), etc... Did I miss anything?
You're wrong about the illegal alien crime levels...
Generally, someone that OVERSTAYS a visa, is indeed not a federal criminal offense, but the person IS removable / deportable at that point.
But a persona that has improper or unauthorized access (crossing illegally) indeed violates Federal criminal statute (USC 1325).
Illegal REENtRY after removal: That's a bigger more serious federal crime under (8 USC 1326).
So please quit trying to make all these folks here as illegal aliens as no big deal....many/most of them are guilty of criminal offenses JUST by being here.
And ALL of them here illegally are subject to immediate deportation.
