Wherever you wore it, no one would suspect you of anything. It'd be great to wear to airports AND court proceedings. Also, during Mafia games. They will be for sale in the moustache store, hear?
Generally speaking when I got to court I'm a witness instead of a suspect, but I think if I wore that the judge would suspect me of something for sure. However, it'd be damn handy on the highway when I'm in a hurry to get somewhere.
