Thing is I don't think we can trust the mexican government that much. They have people all over the place going in and out of that country that they don't really care. If we seal off the mexican border, terrorist would have to go through the airline, a ship, or the canadian border.

No S*** Shirlock, their governments (federal and state) appear to be controlled by several crime organizations. Crime families appear to get voted in and out of office with great cyclicality.
Mexico appears to be an elitist system, with millions of Indian poor people at the bottom who want someone to take care of them (YOU) and a small number of European white familes at the top who want to steal the country blind while they're in office. This has been the modus operandi throughout all of Central and South America for hundreds of years. Periodically an Indian nationalist like Chavez in Venezuela gets in, and this leads to a coup. Then the situation returns back to the two class system. It's sad but there is no hope in Mexico, Central and South America.
So importing their poor only helps the Mexican elite and hurts us taxpayers and our rights as citizens. I read today our esteemed government is enhancing their hospitals with high tech equipment in an attempt to stem the northward exodus to U.S. hospitals. ($$$$)
The best and only thing we can do is build a BEEG wall between us and station some troops there. This problem with Mexico has existed for centuries. They were stealing U.S. cattle in the 1800's and driving them across the border -- just like they do with cars and bicycles today. Read the history of the King Ranch and any Texas history around the 1830's through 1860's.
But now 'there' is 'here.'
