A Man Use Jammer to Stop People Talking loudly with their Cell Phone on Bus from Frod Kelin's blog

Eric, a man in Philadelphia, was tired of chatting on the SEPTA 44 bus talker. According to a Philadelphia reporter, when he did not want to hear the conversation, Eric would open the gsm jammer.

Eric told NBC 10, "A lot of people are very loud, no privacy or anything, and when it gets troubled, that's where I screw the antenna and turn the switch."

Eric claimed that he did not know that blocking the phone signal was illegal and thought it was a "gray area". He said that his impression was that it was illegal to prevent television or radio signals.

But even so, he is not very sorry for his behavior.

"I think I'm putting the law into my hands, frankly, I'm proud of that," he told reporters.

The interference agencies used in this case are illegal, including the possibility of blocking mobile communications in an emergency situation, as they can block other important signals such as police radio and other two-way radios.

But the bigger question is that Eric is not alone in this interfering practice.

Jammers are easy to buy on the site, "Forbes" reported that other people in New Jersey and New York are also using them.
