Well, a long time ago,I happened across a car full of 'detectives'...(defectives ?)..... I nearly ran him off the road with my truck ! He was driving like he'd stolen the f***ing car and he tried to cut me up to get into a particular lane for the traffic lights (a very late manouvre) only I didn't move,so he so nearly took himself out ! Arrogant fucker tried to make out it was my fault....... ''I'm a police officer you knowe'',says he,after he'd jumped out of the car. Oh really....then you should know better that to be driving like a complete twat !....... He tried to get arsey with me,so I told him if he didn't get back in his car and piss off,I would run him off the road....... He clearly didn't like this,so when he got back to the station,he reported me to his boss.
So,I had a conversation with said boss and told him what had really gone on. Needless to say,boss cop backed down and said that he would 'have words' with this detective.....Never heard anymore about it.
So,no....plain clothed cops in umarked cars are NOT allowed to pull you for just anything....
Frustrated Genius ! NOT a girl !!!
