I moved with the majority of the crowd, slithering through the mobs going to fight. I managed to get into a limousine, for practicality sake so as to not go through jostling, and become a 'rogue' amongst them. 

There're many Thompson Submachine Gun ammo cannisters on the floor, and a Thompson Submachine Gun laying upto the seat. Many were empty, and many were not, I attached one to the SMG and turned the safety off, hoping that was enough. A person got into the limousine, and after a few seconds of rummaging, started up the enginge. We drove out.
