It’s a reference to an actual note someone put up and is basically calling them a giant nerd instead of leaving a normal message like “hey, found wallet, call this number”. Although in fairness, the idea is actually pretty interesting because it creates an easy cypher only the intended recipient can crack, thus filtering out cons.
The original note was almost identical, MINUS the Star Trek part.



Considering the LAPD is by many considered a gang in itself, and it’s been proven that within its ranks there are various “police gangs” with matching tattoos and the whole shebang, I have little faith in them being on our side. In case anyone forgets, the TV show The Shield was based on the infamous Rampart division of the LAPD. Or remember who beat Rodney King. Or fucked up the OJ case trying to frame him(when he probably would have been convicted if they hadn’t fucked it up). I only hear of the NYPD getting as much hate as them.
