They need to get the National Guard down on the border...at least until they get the wall built:aok . Actually, a high-profile firefight might be just the thing to get Congress and the President off their collective buts to safeguard the border. Everytime I watch a news show where this is debated, they always have someone on who is against any attempt to stem the flood of illegal aliens from Mexico. Time and again, this unappointed spokespersons for the illegals is asked, "If we don't build a wall and we don't deploy troops on the border, what should be done?" They always answer with something like, "We need to work with our neighbors to the south." They never explain what this means.
Now you have the Mexican government issuing handbooks on how to sneak into the US, where to find water, where's the best place to cross. When questioned about it, the official response is that the main purpose is to save lives by making the (illegal) crossing of the border less dangerous. That answer would make some sense, accept the handbook goes on to cover topics such as: how to blend in once you're in, how to get a drivers license, how to get food stamps, how to get your (illegal) kids into school, and on and on. If the Mexican government is going to continue to undermine our efforts to stop illegal entry to the USA, then physical border security is our only option, IMO.
