US troop presence is scaring the illegal immigrants

Apparently, the US troops are scaring the illegal immigrants-

SAN LUIS RIO COLORADO, Mexico -- The arrival of U.S. National Guard troops in Arizona has scared off illegal Mexican migrants along the border as a whole, significantly reducing crossings, according to U.S. and Mexican officials

U.S. authorities said Monday that detentions along the U.S.-Mexico border have decreased by 21 percent, to 26,994, in the first 10 days of June, compared with 34,077 for the same period a year ago.

Along the Arizona border, once the busiest crossing spot, detentions have dropped 23 percent, according to the U.S. Border Patrol.

I have a question for the Mexican government- Whatcha gonna do about it if someone from the National Guard does detain an illegal immigrant?

The deployment plan has been criticized in Mexico as heavy-handed, and the Mexican government has said it will watch to ensure National Guard troops aren't detaining migrants.
