I don’t agree with your premises. These aren’t elite criminals. They can’t flee the country or go into hiding. For the most part they’re low level offenders that run in bad crowds and made some bad decisions. But they still live in the community and are dependent on it. It is not hard to believe that a constant auditory monitor would change their behavior patterns.

It isnt so much about the kid wearing the device as it as about the environment the kid is hanging around in. the idea of acoustic monitoring is a slippery slope, and is rife with zero days, also sounds like it could be dangerous to the wearer, to be somewhere, and have a government agent call up while a bunch of thugs are present, thugs who now know that kid has a monitor, that a] records a GPS track b] has a microphone that heard what they were saying c] has been recording everything for how long? d] the kids a rat, punish him!

If you get arrested and probated as a result of your friends instigations then you need new friends so the shunning may be good but the physical retaliation risk is another.
