Prisons are some of the least secure environments in the world. They do not rehabilitate, nor do they effectively punish - violent criminals thrive so long as they are more violent than the next guy and able to buy the guards.
People are talking about radio jammers and Faraday cages. As part of a defense-in-depth strategy, maybe. But if we can't stop corruption among prison guards, if we can't expect even basic professionalism, what is the point? I don't want to be subsidizing the creation of a paradise for the most powerful violent criminals to rule over people who lost their way while poor. I don't want to be subsidizing something that fails spectacularly at everything it might be construed as trying to do, except make money for contractors.
We are doing something horribly wrong. Maybe we need to replace guards with a small handful of well-paid professionals in a heavily monitored, regularly audited control room. At least electronic locks and cameras can't be corrupted as easily. Maybe we need shorter sentences served entirely in isolation - there seems to be nothing good about the social life of prison. Maybe we should give up on the communications ban and let them Skype their families and browse Reddit all day - who can they really hurt that way? Maybe we should make prison more or less like day-to-day life, except that you can't leave. I don't know, but it seems like anything other than the status quo is worth trying.
We definitely need to incarcerate fewer people, though.
It does succeed quite admirably at one very important goal -- what some would call the only goal: prisons keep convicts in prison and away from you and me.
(Please don't take this as an argument in support of any position on prisons.)
"Managed access systems can cost more than a million dollars apiece to install. But some prisons have found a way to lower the cost by partnering with outside vendors. In California, for example, Global TelLink – a private company that operates phone systems at many state and federal prisons – installed managed access systems in correctional facilities at no cost to the state, as part of a five-year exclusive contract. (Which makes sense: Global TelLink believes it will make more money from pay-phone fees if inmates’ wireless access is cut off.)"
Fascinating that one of the companies involved in helping to cut off inmate cell phone use stands to make a profit from their activities. I have many gripes with the American institutional prison system, and this is just one small slice of the corruption that drives it.
You can have guard radios talking on another band.
