I was almost involved in a DGU situation where 1 of 2 potential assailants had what appears to be brass knuckles on video, but I'm unsure.

Long story short two guys approach me in a manner that would suggest a fight was imminent e.g. brisk pace, shouting angrily and pointing at me. On video it looks like the closest of the two is getting ready to put brass knuckles on when he sees I'm carrying a firearm and decides to back off. I have the altercation on video but even with the pretty good cell phone camera video the evidence seems inconclusive.Are there professionals who could positively identify an object based on what appears on video (his hand was closed around it but some part sticks out) and in the manner he was getting ready to wield it right before he saw I was armed? via /r/CCW https://ift.tt/2Ptjv23
