There are 3 more universally accepted facts regarding illegal aliens and criminal aliens.
1. The large number of illegals crossing the border allow the criminal aliens to also cross and move back anf forth.
2. Within the country, criminal aliens are hiding among the illegal aliens.
3. The industry producing fake documents that the illegal aliens use for employment is also providing documents for the criminal aliens, enabling the to avoid detection and apprehension more easily.
Which brings me to a last fact that, tho it is not universally accepted, it is widely accepted that if a workable guest worker plan was created and legal status for the illegals in the country were granted, dealing with the problem of criminal aliens would be much more successful.
How many criminal illegal aliens do you expect to register for citizenship Ben? I don't expect many of them to and that's not going to affect the criminal element much at all.
BTW, there will still be illegal aliens coming across the border. Legalizing a bunch at this time won't resolve any issues. They'll still be getting services for free and we'll still have millions more of them pouring in.
Those that don't pour in illegaly will be pouring in under a guest worker program. Shortly immediate family members will be able to apply and come over legaly. If anything, the rate of entry will increase under these plans, although some will be termed legal and others still won't.
Children will still be flooding into our schools, unable to handle them. Hospitals will still be the haven for those without insurance. Who's going to carry insurance if they can get health care for free?
What we are doing is legalizing in part, recognizing that the flood will continue, and accepting the burden the middle class will have to carry on their backs.
This is going to be one big free-for-all, well for all but the U.S. Citizen that is.
