I guess you are for taking people bumper stickers off too. Sorry, but I don't buy it. Bozo's drive with cell phones, advertisment signs, speeders, and while putting makeup on. People can handle a truck with a picture of a infant on it.
This is not a porn issue/nor is this a picture off of rotten.com ... All comparative measures of the two are silly IMHO..

There is a huge size difference between a bumper sticker and the signs on the van.
In the name of highway safety the officer did the right thing.
