They will probably get time served and communtiy service. After the many shootings in various other states, a group of people in military type getup, with an assualt rifle on a very busy bridge is cause for alarm. I would have called 911 had I been there. That many citizens did exactly that is an indictation of the amount of alarm these dunderheads created.
No shit, the had a REAL "Assault Rifle" with NO ammo! Of course you have called 911,
you get scared easily.
