Seven Arizona teenagers used an Obama T-shirt for target practice and posted a picture on Facebook,  causing the Secret Service to investigate.

The photo shows the teenagers in the desert holding guns and a bullet-riddled Obama T-shirt. The Secret Service told ABC's Phoenix affiliate that the teenagers had a right to free speech, but they also had a right to question their behavior.

The Peoria, Ariz.,  Police Department is also looking into the matter, since one of their own snapped it.

"I don't think that the shooting of that T-shirt is that big of a deal,"  Sgt. Pat Shearer, who took the photo, told ABC 15.

Jay Davies, a spokesman for the Peoria Police Department, told ABCNews.com that his office had become  aware of the photo Thursday afternoon after receiving a call from the Secret Service.

"We are doing an administrative review," he said, but declined to discuss the details of the case.

Davies said Shearer was a 25-veteran of the department.
