Even if this was true, it wouldn't change the outcome of an semi-competently planned ambush, especially if they were engaged from outside the range of their guns.

Ambushes probably just haven't been a problem for them. Think, a border crossing is going to be deep in a cartel's territory. Maybe some US citizens should start making things difficult for them.
Also, not the first footage of crossing with guns. There was footage several years back in a border patrol documentary (can't recall the name, sorry) that showed at least one marijuana trafficking escort with a shotgun of some variety.
