do you have any warrants? the cops do that sometimes. they say you won something, and want you to verify all your info, then they come pic your ass up when they see you come home.
i know this guy was all kinds of excited thinking he won a big screen tv one time. they called him saying they were coming to his house to drop it off. he went home from work early to meet them, and ended up meeting with 4 cop cars, and got a free set of handcuffs. they did this because he didnt pay a speeding ticket. i guess they had alot of time on their hands.
