I can't say that I've seen any myself, but I did want to offer any and all PPD characters who don't already have an SG a no-strings-attached membership in "Paragon Police Dept." Founded shortly before Day Jobs first went live, it's pretty quiet these days, existing mostly to provide people with a suitably official SG name under their own, as well as an Invention table, a mediporter and a selection of teleporters (as if anyone uses those anymore).

Faces of the City
Not speaking of the NPC. Back around Issue 8 the Paragon PD made their move from Justice to Virtue for RP purposes... as we were practically harassed by non-RP folk. That being said, I was curious if any of my old colleagues came back or have been back all this time and just haven't played their old toons.
Feel free to post if you've seen random Police Drone folks around the city or isles with a name preferably.
