Well, I wouldn't go as far as saying this should be a safe and sanitized The Sims mod. The engine doesn't really have enough options to provide a totally non-violent gameplay experience, does it? I mean, yea, if we can come up with fun pacifist missions, then by all means use 'em. I know I often wondered why there was no garbage truck missions (good thinking CyQ), and things like pizza delivery in VC were fun too. But Punk Noodles does have a point- Most (if not all) people who play the game expect some sort of, erm, anti-social behavior, so the remove all weapons and such might be a bit odd.
And besides, I'm about half way into modelling the police station, and part of the plan was to have supply and evidence rooms for weapon pick-ups. Then there's the jail cells, which I'd like to have peds locked in, and I was thinking of making one of them a torture/interrogation room complete with bloodstains and a police baton pick-up.
Oh, and I happen to like the idea of random gang drivebys too.
