One of the callers on show 477 talked about those stickers people put on their car's rear window showing their family members and how that might be a security issue.
As I was typing this Jack had the same idea I did on that question...
Make a version of those stickers with everyone being armed. That would rock. I'd buy those. Maybe with a couple of different vicious looking dog stickers to go with it.
Just a thought,
