"Braaains..."

Could those stick-figure families and other decorations on your vehicle be compromising your privacy? The concern is that they're revealing information that "bad guys" could exploit. A stick-figure small dog could mean that burglars wouldn't need to worry about encountering, say, a Doberman. A father stick-figure in a military uniform could mean he might be away from home. "Honor student" bumper stickers provide information about where your kid goes to school.
I kind of liked the rotting zombie stick-figure family I spotted on a vehicle at the URA baseball fields the other day. Surely that would put off a potential burglar! Even the undead cat looks pretty fierce.
