"Unarmed" is definitely false, per the other comments: the FBI confiscated "a baseball bat, a fire extinguisher, a wooden club, a spear, crutches, a flagpole, bear spray, mace, chemical irritants, stolen police shields, a wooden beam, a hockey stick, a stun gun, and knives."

But several people seem to be arguing that only firearms count. In that case: Christopher Alberts was arrested with a handgun and charged with unlawful possession of a firearm on Capitol grounds. Grant Moore was found an with unlicensed gun in his vehicle near the Capitol; Lonnie Leroy Coffman, the same, except it was multiple guns and 11 Molotov cocktails.

We can all be thankful he didn't use them, but a person who goes to a protest with Molotovs does not have personal defense in mind.
