So I am playing the sims 3 and my sims made it to the "Traffic Cop" level of the Law Enforcement career. It told me that he can now arrest and stuff like that (Yes I know that you can't really arrest) but that made me think. "What if my sim could arrest?"

Well if you know me, and you don't because I am new :D, you would most likely know I play the sims 3 with a ton of mods. Most of them are NRaas mods.
I do have the story progression mod, master controller, and a few others but that isnt important.
With the NRaas Story Progression, I get pop ups of everything that goes on in my town. It is annoying buy hey, atleast I know they are doing something...
Well every so often, I get a post that tells me someone was fighting, money was stolen, or something bad has happened and I am like "Hey, wait. My sim is a cop, why can't I do something about this?"

And that's what brought me here today. I want to know if anyone out there can tell me if there is a police mod that allows my sim to make arrest. I would love it if it was apart of the NRaas mod but it doesn't have to be. Just as long as it is compatible.

Any help or information about there being such a mod, would be lovely!

Also, if you need more info about my game to help me find a mod, just ask! :D

The enhancement is being considered for Nraas DebugEnabler. It's on the list:
http://nraas.wikispaces.com/DebugEnabler+TheList

"Interaction to initiate an arrest situation on any sim" I believe would be close to what you would want, but there's no telling when or if they will include it. Maybe you can ask igazor about this. @igazor, a little help?

Police sims at level three and up can arrest burglars on their lots, unless your sim has the Good trait. Also sims who have the hidden trait 'Can Apprehend Burglars' can, well, apprehend burglars too.
Also you might be interested to know you can change the number of stories you get from Story Progression by clicking on the City Hall and going to Nraas > Story Progression > General Options > All Stories, and from there choosing who you want to receive notifications from.

I have downloaded the debugger but I have yet to find the action to arrest someone. Would you happen to know?

It's not included yet.

That list I linked to has interactions that they are thinking about adding in the next version of the mod. It's not in any of the previous versions. When they add anything new to the mod it will show up either in the testing section here:

or the newest mod updates here:

Oh sorry, didn't see this question until now; the @ call/page didn't land in my inbox, maybe due to the comma immediately following? I'm pretty sure the DE command under consideration is to force a sim to be arrested by an NPC Service Sim, not to arrest someone else. Unless you were planning to have this cop apprehend and arrest themselves. Which, in public, might still be illegal in some parts of the world (will have to check on that).

The thing about DE is all that mod really does is expose in-game commands already put in place by EA to a user interface. It's not like it can add anything new that isn't already there, used or unused, in the game code in some form. That's why DE has such a relatively short list of items on its Wish/To Do List page, whereas some of the others go on and on for many screens.

The idea of an active cop going around arresting other sims sounds like fun, but way outside the scope of what NRaas typically covers. Though nothing to lose by stopping by and asking if anyone has heard of a modder working on such a thing.
