If there is no detention space and no criminal record or other cause for concern, undocumented immigrants are released with a promise to return for an immigration court hearing. Court figures show that more than 88 percent do not return.

Yep..the criminal data bases of Central and South America are pretty up do date no doubt ;)

And their police forces so willing to cooperate with an America they all want to get to but at the same time hate..

no criminal record

Good point. How anxious is the police force in a Mexican town to have a drunken trouble maker sent back home? And, how likely is it that the illegals use their real names when they are detained? The criminal background check is probably next to worthless.
