It makes zero sense to even have a border patrol if these policies continue. You pick up an illegal immigrant, process them, house and feed them, then let them go free with papers to travel anywhere in the U.S. 
OK now I get why so many people are crossing. There is no reason to worry once you make it.

A spokesperson for the U.S. Border Patrol recently confirmed such anecdotal evidence to be part of a larger strategy to focus resources away from individuals “posing no threat to national security.”

“In an effort to maximize resources and focus on the uptick in apprehensions, RGV Border Patrol Sector has begun implementing several steps,” a Border Patrol statement read. “These efforts include, transporting detainees to other sectors within the South Texas Campaign AOR, temporary reassignment of agents from other sectors into RGV and temporarily issuing a notice to appear for immigration hearings to family units posing no threat to national security.”

“While ICE is only releasing individuals it deems to be non-threats to national security, most of them will abscond and never show up for their immigration hearings,” Longmire said. “Immigration reform means different things to different people, but the inconsistency in how these band-aid policies are being applied is incredibly frustrating for people who want to see real change–and improvement–in one direction or another.” read more
