Legal FIRST, just like my law abiding grandparents did. I have not forgotten what they and others like them did to get here, adapt and become an American. Sorry, those here illegally are criminals and should not be rewarded in any way, shape or form. Additionally, they are a slap in the face to my ancestors and many others who followed the law to get here.
Cost (and who pays) is just part of it, FQ. Police academy trainers have told me gangs and terror types are keeping members 'clean' and then trying to get them into the academy or the armed forces for obvious reasons. Seems some Islamic terrorists have already gotten into the military, from recent experiences.
Why in the hell would we facilitate their efforts by doing something like DREAM?
