Scanning the airwaves電波 for police radio conversations is something professional crime reporters have done for decades. But now a whole new group of people are embracing擁抱 this old-school technique.
In Los Angeles a growing band of residents has invested in scanners to monitor police conversations and spread傳播 what they learn across the city on the social networking site Twitter. Between them they now have over thirty thousand Twitter followers.

It's been an absolute revelation啓示, she says, to find out what's really happening in her area, the crimes her fellow同伴 residents would normally never hear about.
Alex Thompson:
"When I first got the scanner for listening I was in shock – the way I described it I hid under my desk sucking my thumb拇指 for two weeks in disbelief懷疑 of what I heard. But the reality現實 is this is what is going on in my neighbourhood."
