Vox has a piece discussing a proposal to replace prisons with mandatory labor and geolocation--i.e., let the convict work to compensate his victim or society, but with an ankle bracelet.
It appeals to my squishy liberal heart. However, I note that the Kentucky doctor who bilked Social Security of hundreds of millions of dollars by approving disability claims has now vanished. He was out on bail with an ankle bracelet, but cut it off and vamoosed.
That's not to say the proposal is totally impractical, but it could work only by a trade off of the difficulty of removing the bracelet, the likelihood of evading recapture, the gains of freedom, and the consequences of recapture.
