I can't believe you would even ask if that stupid **** was true.
I had a guy about 10 yrs ago try to pass off that he was just back from Marine boot camp. After doing some "research" and finding out he was a habitual fake, I approached him and asked for a few minutes of his time. He agreed & we stepped away from the group (including his girlfriend) and I proceeded to let him know that I'd figured out his game & that if I'd ever heard of him spreading his lies about being in the Armed Forces, I'd make sure he met a few actual Marines... All of this was done in a quiet tone, so as to keep our chat private. I've never seen, nor heard of him since...
Maybe this guy needs to meet a few ACTUAL SWAT OFFICERS? A quick chat may help him learn a valuable lesson?
