Why? Will some passing Hollywood producer please get the Sheriff's Department in Lost Hills, Malibu their own reality TV show or something. Or at least the congressional medal of honour for daring to take on the evil might that is Shannen ‘Brenda Walsh' Doherty!

The real-life mean girl cruised into their offices last week to complain about the paparazzi following her, only to discover that none of the cops knew who she was!

After revealing that she didn't feature on his fame radar, the Deputy asked the other cops and drew a blank, causing Shannen to storm out of the station.

Getting on the wrong side of Brenda? They're gonna need police protection.
