I don't know if those blimps are any good, but it's very clear that our government doesn't care much about the folks who live along our southern border. I think the most cost effective thing the guvmint could do is to put a bounty on illegal invaders--them and the horses, planes, boats, vehicles, etc. that they ride in on. And it shouldn't matter what shape the offenders are in when the bounty is applied for.
