I think we should help Hollywood and TV show makers out by briefly explaining what some technologies actually do.
Like the 'MasspecDNAtransmoglifier' - where you can get a sample of DNA, like skin cells from a crime scene, put it through the MasspecDNAtransmoglifier where it builds a full sized cardboard cut-out of the person in the clothes they were last wearing, so you can place them around the city with the sign 'have you seen this man? Wanted for questioning'
Or the 'WiiFinder' - Where criminals can be found be searching the Internet for the current location of that persons active WiiMe. Using Biometrics stored when you using WiiFit the police will be able to find the criminal when standing on the balance-board doing hola-hoops or ski-jumping.
