I suppose the only way this could get worse is if the Drug cartels start using an army to start taking territory in Arizona like ISI in Iraq, and Obama still refuses to help them.
Accident or not this isn’t the first time Mexican military personal and equipment have opened fire at American personnel specifically border patrol.
Usually it is to help the drug cartels else where. I remember stories in Texas of them using tanks against the border patrol. I really do think our boarder patrol is out gunned and certainly out maned for the increasingly aggressive forces across the board. They need closer military support.
Did they shoot back? I sure would have!
