History, Chief. They were fleeing in droves long before Ike's troops came through.
“When the Operation kicked in, 4,800 illegals were arrested the first day. Arrests stabilized to about 1,100 per day. Note that this was accomplished by a govt. force of ONLY 700 men! The figures as to how many illegals were actually deported are disputed, but it was certainly in the hundreds of thousands — with a 6-figure number also for those who fled back to Mexico to avoid being rounded up.”

Surprising how, 50 years ago, the same problems existed that are plaguing the Southwest today. A roundup enacted by a strong leader did not ruin the local economies nor foment chaos in Mexico (though the latter would be best for its citizens today, IMHO).
Just like the terrorists have redefined war Mexico has redefined invasion. In each case doing nothing equals giving up, and failure is not acceptable. If there's any chance civil assembly/protest/whatever may help get the CinC to stop acting like McClellan waiting for the breeze to blow just right and perform his sworn duty then these people have the right, yea, the civic duty to do so. The smugglers and their corrupt, uniform-clad protectors have lately taken to shooting into our side of the border and crossing over with impunity. These citizens, especially those in Cochise County, deserve some real help.
What law enforcement they have available is really stretched thin.
Heck, all you need are a few more border patrol officers. According to ol' Spiff there: "The BP has most of the border effectively covered. We need rapid reaction troops to cover the hotspots."
Since the border patrol apparently has most of the border already effectively covered you just need to fill in the gaps with some more border patrol and maybe a few more local cops for these hot spots. No need to bother the military for a couple of hot spots.
