Evidently, there is a LOT of truth in this version of the incident.

AUGUSTA, Ga. - A U.S. Marine reservist collecting toys for children was stabbed when he helped stop a suspected shoplifter in eastern Georgia.
Best Buy sales manager Orvin Smith told The Augusta Chronicle that man was seen on surveillance cameras Friday putting a laptop under his jacket at the Augusta store.
When confronted, the man became irate, knocked down an employee, pulled a knife and ran toward the door. Outside were four Marines collecting toys for the service branch's "Toys For Tots" program.
Smith said the Marines stopped the man, but he stabbed one of them, Cpl. Phillip Duggan, in the back. The cut did not appear to be severe.
The suspect was transported to the local hospital with two broken arms, a broken leg, possible broken ribs, assorted lacerations and bruises he obtained when he fell trying to run after stabbing the Marine.
The suspect, whose name was not released, was held until police arrived. The Richmond County Sheriff's office said it is investigating.

OK, there is a little bit of truth in the story, but not a lot.
Go to Snopes and actually read the whole thing. Yes, the shoplifter did stab one of the Marines, and yes, the other Marines did hold the shoplifter for police. But the part about the shoplifter being injured is complete fiction.
