Something that I didn't see much in the way of explanation in the SotB book was the legality of carrying, or even openly carrying, firearms and other weapons in New Angeles. Earth Station has a backscatter arch looking for weapons. And there are rules and talents concerning Restricted (R) weapons. But nothing really touches on the general legality and attitude towards weapons in public. (I didn't see anything in The Worlds of Android either.)
Can PCs, who generally don't have their own private transportation, just load up their gear and get on the metro without hassle? If they can't, will a taxi take them to their mission while toting all sorts of weapons? How do others handle this in their games?
