If I'm not mistaken, the CCTV footage was not as useful... what did help was the one man who took a picture of the bomber (unbeknownst to him at the time), and more importantly, the unfortunate man whose legs were blown off at the knees who valiantly gave an ID from his hospital bed.

Excellent points!

This has VERY interesting possibilities for digital forensics as well. I get the feeling that the bluecava guys aren't even aware of that possibility yet. This would allow web interactions to be more thoroughly traced to a particular machine. Given the ability of most companies to put a particular person behind that machine (whether surveillance or electronic controls), suddenly your machine AND your interactions are subject to investigation at any time.

For those of us with "soft" teeth (and you know who you are), this is a REALLY *bad* development! I don't want to re-grow my teeth. In fact, I want to get rid of the originals! I would REALLY like to see advances in implant technology, and a reduction in price. I'd like to have all my teeth replaced. I've already had seven root canals, at least two crowns (with six more on the way) - why can't I just get them all replaced?

(As an aside, most dentists seem to want to "save" teeth. I can't see any reason for this. Furthermore, implants are expensive - to have my 28 teeth replaced at $4k/tooth would cost $112,000. If I had the money I would do it.)

Thanks - I came here to post this as well. "Broadcast" would be much more appropriate.
