Regardless of where he is or what laws have been broken to get him there, Nicholas is still first and foremost a cop. A cop with plenty of time on his hands, as he is not a member of the police service here -which frustrates him to no end, because really, if he is going to be abducted to assist anywhere they could at least let him do the work he knows best- and nothing in particular to investigate. So he's acquired a copy of the city's legal code and is occupying a seat outside a café with a glass of cranberry juice to study the laws.

Of course, if he sees anyone obviously breaking any sort of laws, he will flag them down. Although Nicholas is just suspicious enough of everyone and everything that even a person who simply looks out of place is going to be regarded with suspicion, if not outright stopped.

He'll likely end up making quite the scene of he keeps this up and stops the wrong person without having the authority of Darstone's police service to back him up.

((ooc: Feel free to either try to stop him, be someone he accosts, or come up with some other reason to approach))
