Removal of maintenance cameras

[Kotlol]

it's easy enough to prevent the ai from tracking your movements since not all of them know to track any Unknowns prowling the station

that, or do some prepwork with some stable mutagen to conceal your crimes

"Unknown spotted, please investigate"

Security catches the unknown.. it's classic, they are smacked. It's over.

"Use stable mutagen"
Not every antag is a scientist.
