Ha! YEAH you are. =p
That'd be more of an open-carry permit, wouldn't it?
I think it'd be a cool idea. Of course, they should be NOTORIOUSLY difficult to come by. Can't have every weeflerunner cruising around Corporate Plaza with their Barrett .50 cal rifle or their rocket propelled grenade launcher slung over their shoulder, neh?
Perhaps police possess the cybernetic enhancements allowing them to detect concealed weapons?
There's an opportunity for an interesting gameplay dynamic here: as long as you have no criminal record you can buy a permit relatively easily, provided you have the cash. So...
... if you are a rich corporate boss, get someone else to do your real dirty work for you or maybe pay off the police to overlook your record. You get your concealed weapon.
... if you are a thief, make damn sure you don't ever get caught, keep your record clean. You can have your concealed weapon.
