Kase Cosgrove, a U.S. Marine Corps veteran and safety volunteer attending the protest, said he approached the man after other protesters told him the man was armed and spitting and shoving people while walking through the crowd.

Cosgrove said he walked toward the man and saw him tapping on what appeared to be a handgun and pulling it out of its holster to show people he was armed. Cosgrove approached him and attempted to talk to him but three police officers quickly arrived, retrieved the weapon and put the man in handcuffs.
