We found that by putting all humans in cages with no ability to contact eachother or interact with the outside world crime fell to almost zero.
Not a bad idea. Just launched a company around that concept, with a full range of cage options. I bet ICE will subcontract to us.
Another great innovation was implanting chips in people's brains that send everything they see, hear, say, and think to the nearest police station. That sure helped reduce crime at the low, low cost of an obsolete concept called privacy.
