Burglars? Haven't seen any

Burglars would be great. Actually, you know what be ever greater? Adding burglars and then having a burglar section in the criminal career of which you can join and you'd have to complete certain tasks in order to get into and out of the house without being caught. Things like disabling the alarm system, getting into the house buy a window, making sure that you don't go into a room with sim unless they're sleeping, sticking to the rooms that have the lights off. You would have to steal a specific item in order for the heist to be successful. I think it would be a fun addition. But really, just the addition of burglars would be fine enough, the rest of my comment is just a pipe dream.

And maybe, just maybe when/if they add cars they'll bring back firefighters (career opportunity?) and police NPCs. That'd be cool.
