In the future it will be impossible to commit crime and get away with it. For one thing, you'd have to leave your phone at home. Surveillance becomes continually more pervasive, including self-surveillance like posting on Facebook. This isn't new but it bucks the trend of the last few hundred years. We are more like living in a village or even a hunter-gatherer tribe where everyone knows what everyone else was doing. Privacy barely existed and certainly wasn't fetishized like now.
My personal experience in hanging out with delinquents is that boredom is (was) a big cause of youth crime. One thing this report doesn't mention is that online people are, I think, getting more socializing influences online which reduces crime.
And kids are smarter. Crime doesn't pay, especially at the lower end.
