More and more corrections officials are using electronic bracelets to keep track of prisoners. Slate senior editor Andy Bowers explains why these devices are so easy to remove, and how prisoners can "disappear" from under the watchful eyes of prison guards.


If Mark Emery ever is convicted in the US, he may someday be required to wear an electronic monitoring bracelet of the kind famously worn by Martha Stewart earlier this year. One was also worn by the Puerto Rican nationalist leader Filiberto Ojeda Rios before he snipped it off 15 years ago and went on the lam until last Friday, when he died in a shootout with FBI agents. That got the Explainer team at the online magazine Slate wondering just how easy is it to cut off one of those things. Here with the answer is Slate's Andy Bowers.

ANDY BOWERS reporting:

All you need is a pair of scissors. Electronic monitoring bracelets aren't designed to stay on at all costs. A device that needed special tools to be removed would pose a serious health risk to its wearer. A bracelet might get caught in heavy machinery, for example, or paramedics might need to remove it to provide emergency medical care. Most of the monitoring bracelets on the market can be easily cut in two or even ripped off if enough pressure is applied. Of course if you slice through your bracelet, you'll probably set off an alarm. A radio transmitter embedded in the bracelet is programmed to send a distress signal as soon as it's tampered with, although bracelet manufacturers won't discuss the specifics.

When a criminal has served his time, removing the bracelet is as simple as cutting it off. The actor Robert Blake wasted no time in removing his monitoring bracelet after being acquitted of murdering his wife. He asked the crowd outside the courthouse for a cutting implement moments after the verdict.
