It's a standard of our judicial and penal systems: Rehabilitate the criminal, provide him/her some education, training, and socialization. Help him become a reformed and useful member of society.
There's not a lot of proof that this works, except in a few cases, and it's not universally accepted as appropriate policy. But let's assume it's correct. COULDN'T WE PLEASE WAIT UNTIL THE BAD GUYS ARE IN CUSTODY BEFORE WE EDUCATE THEM?
I've been struck by the recent case of the journalist James Foley, beheaded by ISIS (ISIL if you prefer). Ever vigilant, our media, in a rare departure from their humdrum lives of reporting what celebrities are wearing at the Emmys, have taken to full and frequent reporting of how the murder is being investigated. Experts will analyze the visible part of his eyes and run them against facial recognition software. Other experts will analyze the bumps under his mask and use facial reconstruction. Together, they have come up with a sketchy image of the executioner.
There are countless examples of this kind of thing. On a simpler level, local news reporters love to tell tales of the "dumb crook" who burgled someplace and advertised the stuff he stole on Facebook.
I don't understand why we do this to ourselves. In an effort to prove that they're smarter than the crooks, or just to demonstrate that they are as hip as the tv shows we see, law enforcement authorities are releasing all sorts of details about techniques they use to combat crime. Once such information is out in the public, the value of the technique is vitiated. In efffect, we teach future lawbreakers how to be more successful.
It's silly and expensive. Let's stop releasing this kind of information.
