To: cypherpunks@toad.com KK> Bear in mind that OJ himself placed a call to 911. You sort of expect KK> to lose some of your privacy when you do that. Actually OJ called his ex-wifes condo, her father answered, OJ said he was coming over to kill himself, the father ran out yelling "Call 911". But yes, I would want my cell phone number to appear on the 911 dispatchers screen too. * RM 1.4 B0037 *
This is kind of offtopic, but I wanted to correct something. At least from what I know, if you place a 911 call from a cellular, it doesn't pass any information on the phone number (or car) at all. This was originally posted on from the telcom groups. I later tested it in some respect. E911 uses ANI to get your number, so I did a check on ANI from a cellular. The number ANI gets is a call-out-only line from the cellular MTSO. So how'd they find him? Your friend comes along with you on your run from the cops. You take his bronco (dumb move #1), you use HIS cellular phone not a payphone (dumb move #2), you place long calls so the FCC can track you in one of those nifty vans you only see in LA and NYC (dumb move #3), and you call people who the government would expect you to call (dumb move #4). Well, with a simple addition they could have the phone company add ANI to all his family/friends. Then they would know its a cellular, and knowing that, they kinda guessed who owned it. I don't give them that much credit though, probably a tip from a friend/family told the LAPD/FBI/CIA/NSA/FCC/BLAH that he was calling from his friends Bronco. Then its a matter of waiting for another cellular call. At that point, you'd know the tower (about a one mile radius) and then you'd could easy send cops or a trianglulation van to hunt him down with a 99% sucess rate. Why anyone would attempt to run like this baffles me. Unless he was just stalling for time, he did things I think my little sister even knows NOT to do in that situation. Once again, sorry for the blurb, lets get back to cryptography.
