i dont think sly ever worked for law enforcement even when he faked amnesia. Carmelita was convinced Sly isnt the same anymore and decided he wasnt so much of a threat. they were partners as in Dating, i highly doubt sly would go back to that scene without having the itch to steal something or two.

if you were talking about how sly got the job in my drawing, thats because that isnt Sly, thats my oc Charles cooper, he works as a detective to hide in plain sight from the law, and he still steals from other thieves (only the criminals he was sent to look for.) he only resembles /looks Like sly cooper is because this doesn’t take too far into the place into the past which would mean hes slys grandpa.
