Top cop Predicts Robot Crimewave:
Technology such as cloned part-robot humans used by organised crime gangs pose the greatest future challenge to police, along with online scamming, Australian Federal Police (AFP) Commissioner Mick Keelty says.

The Hell. The Commish may have a few good points about combating online crimes like identity theft and internet scams, and even makes a few good theoretical reaches into policing Second Life for cybercrime, but then the pills kick in and he goes on about part-human, part cloned robot people capable of leaping tall building in a single bound.
Too may nights up late reading comics under the covers Officer?
“You could (also) have technology acting at the direction of a human being, but the human being being distanced considerably from the actual crime scene.”
As Mr. Robotics says “One could also drive an RC car into a bank with a holdup note. Doesn’t mean the robot armies are coming about any time soon.”
Granted, remotely-programmed vehicles (an autonomous robot with a specific directive) are harder to track to the operator rather than a mere-smear RC controlled car, but still, the technology is so very far off that chances are the science and practice of law enforcement will have evolved into something wholly different from what it is nowadays.
Stand down, AFP, Skynet has not yet become sentient. We’ll keep you posted though.
