Camelot Gardens

not a village or a town, camelot gardens was what americans call a 'subdivision', a gated neighborhood in outer parts of a city where the rich feel safe in their identical homes that are protected by a wall and secure gate. the cop was a security officer paid to patrol the premises.

It's a private gated community. I don't know how common they are, but in countries like England they are cropping up in greater numbers in the past couple of years.

Anyway, since the community is owned by a private entity (most likely a homeowner's association made up of the people who own the houses), the security guard has authority to enforce the HOA's rules. Despite that, the local/state/federal governments still have ultimate authority.

Though the security guard did seem to overstep his authority in some cases, especially when he showed up at Trent's trailer trying to play supercop. Since he was no longer on Camelot Gardens' property, Trent was right not to answer his questions because, as Trent said, he's not a real cop.

My theory is that the security guard is no longer a police officer because he got fired for being abusive. After he punches Trent, he says "I might not be a cop anymore, but I can still act like one." Apparently he thinks being a cop means beating people up.
