Another suggestion is have some of the illegals build a wall, (if not only in Arizona where illegal entry is worst) as recompense for their criminal act.
Another suggestion is to fine all those employers treble damages (ss, fica, ui, etc) for their illegal employment practices.
And yes, have some of the remaining illegals do it the proper way, through INS, with the waiting period that all the legal immigrants have been forced to endure.
As a P.S., I think the march organizers, as well as the marchers have come to realize that while we cherish our freedom (right) to burn our own flag, we frown on any illegals doing it at the very same time they are trying to gain entry into our country, whether that be by legal or illicit means. Since they seem to dislike Mexico so much, I do not understand why they do not burn the Mexican flag. Ill laid plans...
