I wander if they even know that flying the flag upside down is an Military distress call.  IE radio is out, and runners can get out or in. 

Prolly not, they did it to be disrespecful and didn't even realize that placing the Mexico flag above the U.S. flag is a violation of federal law or that by flying it upsidedown is a distress signal. You can't even fly a state flag higher than the U.S.

Hmm..reminds me of one day at work when a customer asked me if i was legal just out of the blue. Ya I'm Hispanic but even still, I was at a loss for words.

I've had people ask me the same question about my employee's too, as far as I know they're all legal. At least that's what their docs. say.
