Not really being a fan did the invisible man rob banks?
Just saying somebody armed with a ski mask, and a can of spray paint, can render a glass wall opaque within minutes. While cleaning it off, will take hours.
Thats gonna take a lot of paint and a whole lotta time.
Meanwhile the border patrol will be playing Pinochle.
Or a super soaker, or water balloons filled with paint. It takes 30 seconds, far faster than the border patrol can respond to.
You're sorely lacking in basic security systems.
