Mexico tightens border security
Mexico has deployed soldiers to the border. And, this time they're on Mexico's side of the border.
Specifically, they're at bridges between Brownsville and Laredo. The Border Patrol wasn't informed of this new move and they only noticed it because much less traffic was coming through.
I think this can be considered to be two things: a) a preposterous attempt to show that that corrupt country is doing something about drug trafficking, and b) an attempt to show the economic power of legal visitors from Mexico.
