Window Decor

The other day I saw an interesting rear window decoration. On the back of a medium sized SUV, the sticker showed a shotgun, bolt gun, battle rifle and what may have been a 1911. Now, I am a gun guy, but I wonder about the wisdom of such blatant exhibitionism. Say you're going hunting, or maybe to the range and you stop for food. Doesn't this just scream, steal this here?
