Los Angeles Times: A commuter in Philadelphia recently confessed to using a cell phone jammer on his daily bus ride when he felt his fellow bus riders were being too disruptive with their cell phone conversations.

The FCC pointed out that jamming devices aren’t selective: 911 and other emergency calls could be jammed as well, and the range of jamming devices can extend far beyond the space the user intends to control.
