This is the law - I want them to enforce it. The Gov't is conducting sweeps on airports & finding many illegals. The INS conducts raids as part of their job. If the penalties to employers were severe enough to cause disruption to business then not many sweeps would need to be conducted before businesses would begin to quit hiring illegals.
As far as deporting other illegals, law enforcement agencies currently do NOT hold or turn over to INS the illegals they stop in routine traffic stops or other arrests. If I'm stopped, yes I produce a valid drivers license, not a Mexican ID. When I get a job I produce a valid Social Security number.
The illegals need to be sent back & after meeting a means test, legally apply for entry to OUR country on THEIR side of the border.
I suggest we work to stop more from entering the country through better border management. At the same time we need to integrate the people that are here now into the culture. The risk is that they are not integrated and become disenfranchised and hence are multi-generational welfare recipients. Morriss idea is a decent step in the right direction.
