What would be Mexico's official response if I decided that I wanted to cross into their territory with no documentation and pretty much do as I pleased while I was there, never paying taxes, getting a driver's license, or in any way cooperating with the local authorities.
You think they might have a problem with that?
All the wall will do is make border crossing a controlled process where people will have to comply with our laws. What's wrong with that?
Like if you were from Guatemala trying to sneak into Mexico?
"Many of the illegals in Mexico, who emigrate from Central and South America, complain of "double dangers" of extortion by Mexican authorities and robbery and killings by organized gangs."
"The State Department's Human Rights Practices report, released only last month, cites abuses at all levels of the Mexican government, and charges that Mexican police and immigration officials not only violate the rights of illegal immigrants, but traffic in illegal aliens."
