Yes that happens also—sometimes the coyotes leave the aliens in the Mexican Desert next to a mall in Chihuahua (that is very modern and looks better than anything El Paso or Tuscon has) and say—Bienvenido a los Estados Unidos!
Big deal...
The Mexican Army hunts down and robs, beats, imprisons, and sometimes kills their illegals.
Hey, you can get in trouble with the UNHRC for saying something like that. You're supposed to report that kind of military insensitivity to them first. With lots and lots of documentation.
Otherwise, it's just wind shaking the dust from the chaparral.
