4 robbers were trying to steal a celica of a mafia and got caught red handed, they were hit till unconcious. When awake, they found themselves burried up to their necks, they couldnt move L&R or U&D, and each of them's now wearing a hat. The mafia stood over them and says:

"So you punks of got guts to steal my beloved celica uh? I put so much time and effort into this car, let me tell you soemthing punks, even if you managed to steal it you wouldnt get away with it bcoz everyone will knows abt it and they will hunt ur asses down...why? becoz im on 6gc.net and everyone knows me..Now, I can let you guys all go if one of you can tell me the colour of your hat, only one try. If you get it right you 4 can walk outta here with my celica but if you get it wrong, ur history. I'll give you 15 mins"

Heres the catch. Three of the robbers are burried on the one side of the room while the remaining robber is on the other seperated by a wall. There are no mirrors in the room, they are not allowed to talk to each others. The guy behind can see the guy(s) infront of him but he cant talk to them whatsoever.

They know that there are 4 hats, 2 blacks and 2 whites.
One of them knows the colour of his own hat for sure but which one and how does he knows...????

btw....one of the guys asked the nick of the mafia and apparently hes known by the name of "Coomer"....sounds familiar??? jk
