I am with jssgbsn on this one. Nothing was proven either way on this, but I do know that you can buy complete uniforms rank, patches and all. My dad is a colonel in the Army and I can wear his uniform around and not many people would know, I guess other than age. I have the same last name and the uniform is real. I know with the video games and air soft stuff getting more and more popular I wouldn't be surprised if there are people faking it. Not my place to call them out on it like these guys did.
Who knows this guy may get flustered under pressure and with people yelling at him he didn't know what to say or do. I wouldn't give some random guy my ID to prove anything.
