Here’s some snippets from the Orange County (Calif) Register from Oct., 2007:
LAKE FOREST – SWAT officers expected to find a victim shot to death, drugs and a belligerent armed suspect when they surrounded the home of an unsuspecting couple, but found they were only a part of a false emergency call caused by a teenager who hacked into the county’s emergency response system, authorities said.
On March 29 at 11:30 p.m., authorities allege, Randall Ellis, a 19-year-old from Mukilteo, Wash., hacked into the county’s 911 system from his home and placed a false emergency call, prompting a fully armed response to the home of an unsuspecting couple that could have ended tragically.
....Ellis selected the couple’s name and address at random and electronically transferred false information into the 911 system.
....False 911 calls are placed all the time, McHenry said, but he said this is the first time someone has hacked into Orange County’s system and created a false call in this way.
.....Other law enforcement agencies have seen similar breaches into their 911 systems as part of a trend picked up by computer hackers in the nation called “SWATting”, Barnes said.
Wow, that is high tech right there. I think I heard about it on the news even.
If a dozen hackers are inserting false reports into 911 systems, then a hundred are probably quietly watching them and tipping subjects off.
