Too bad state troopers didn’t lead the field trip all the way across the U.S. border and then left them there.
It would be extremely poetic if some of the "teachers" and students were found out to be illegal aliens and the AZ authorities put them on the other side of the border!!!
"¡Porque! ¡Porque! Where is my nino?"
"Sorry, Lady there's nothing we can do about getting your kid back over the border. This seems to be YOUR signature on the Che/polPot/Stalin/Marx/violent/racist/hatred promoting/communist/revolutionary/brain deficient field trip permission slip."
