Transcript for Stolen Valor: Imposters Pretending to be Soldiers
Tonight, stolen valor and the case of a new possible impostor. A man wearing an alleged military uniform. Here's Matt Gutman. Reporter: A dressing-down for a man accused of dressing up, as a soldier. It's called stolen valor. I did not steal anyone's valor, I swear. If I had anything else to put on this morning. Reporter: At Fresno airport this week, Christian palmer, a former combat engineer, notices the man with the Starbucks coffee cup was wearing his uniform incorrectly and confronts him on camera. The man, finally admitting -- It's my stepson's uniform. Reporter: And this man, busted down on black Friday at a Pennsylvania mall. Why is your flag so low on your shoulder? It should be up here. You got me on that one, bud. Reporter: Fellow shopper and purple heart recipient Ryan berk says the man in the army ranger uniform, Sean Yetman, is a fraud. We checked. The army has no record of a Sean Yetman. And our repeated attempts to reach him went unanswered. It's frustrating, because you serve with good men who have either lost their lives or have been seriously wounded. Reporter: It's not illegal to wear a phony uniform, but profit from those unearned medals or badges, and you've broken the law. Earlier this year, we confronted the man in this video, A.J. Dicken, who claimed to be the most decorated Navy S.E.A.L. Ever. Who convinced a pair of Nevada doctors to invest nearly $1 million in his company. But according to the government, he never served a day in the military. Reporter: Some in the S.E.A.L. Community say you're not a commando, but a con artists. Which is it? Now, real soldiers are reclaiming that stolen valor with viral videos. Matt Gutman, ABC news, Miami.
