I'm always astounded by the complete ineptitude of politicians when it comes to anything with a remote whiff of high tech.
It's clear that they've been watching too many movies where the CIA/NSA/FBI/Mossad/MI5/MI6/[insert other security service here] have their massive database at their fingertips and can track everything that's happening on their network. They've seen too many movies where Kevin Costner/Mel Gibson/Tom Hanks/Meg Ryan/Matthew Broderick/[insert other actor here] hacks into the security service/military/[insert other target system here] and foils the plot to blow up the world/starts the end of the world/[insert other disaster here].
The Italians buy this stuff hook line and sinker, they force me (a non-Italian) to change my passwords every 90 days (because I work for a global computer company). They've demostrated with that that they don't understand the Internet and the global nature of the internet. They've failed to notice that the child pornography moves from one IP addr to the next every day (and when we switch to IPv6 the bad folks will switch IP addr every minute if they need to.
The world is full of paedophiles, the world is full of bad people and the internet means that everyone is a child pornographer. Except that's not true only a tiny number of folks subscribe to that stuff and sometimes the authorities get ahead of them, sometime they're ahead of the authorities (just like the spammers and phishermen). Chase the server not the client, when you find the server it's logs will have all the stuff (punter's credit card numbers, ip address, whatever) that you need to find the ponces who peddle and trade this stuff. It'll be located in China or Russia or other Eastern European countires (it always is), In the UK I would get years in prison and registered on the Sex Offenders Register for life just for accidentally finding a child porn image on Google Images and looking at it so it's unlikely to be here.
This is not the way to control the problem. The way to control the problem is not the folks looking at this stuff, it's the folks publishing it and when you catch them castrate them (that's probably too weak a punishment). Sniffing my exceedingly boring internet traffic doesn't work - because I know how to use SSL and I know how to use an internet proxy with a secure VPN and if I were inclined to want to use child pornography then those are the first two requirements.
