Cellphone jamming system tested at Maryland prison
COLUMBIA, S.C. (AP) — Federal prisons officials on Wednesday tested a jamming technology inside the walls of a federal prison, a rare move that authorities said they hope will help combat the danger posed by inmates with cellphones.
The test was conducted over several hours Wednesday morning at a federal prison in Cumberland, Maryland, Assistant Attorney General Beth Williams told The Associated Press as the testing took place. Williams didn't give specifics of how the test worked but said it marks a step in the fight to cut down on inmates' ability to communicate unsupervised and carry on with criminal efforts.
