A friend of mine found this appropriate headline/photo combination on his smart phone and took a picture of it.
If you can't read the headline it says "Midday Muskegon: Four men rob elderly Muskegon man using a walker..."
The caption next to it is a photo of Gingrich, Santorum, Romney, and Paul.
For the record, the man who was robbed was not physically harmed. The robbers took his cash. Hopefully the perpetrators will be brought to justice, and more importantly here's hoping he can feel safe at some point soon.
To confirm the photo wasn't photoshopped, I found it myself as well...here's my own screenshot:
