Seriously ... most hackers are caught as a result of them bragging in forums, blogs or usenet sites.
A few stupid enough to leave a trail to a fixed IP also get caught.
My advice is to do the right thing and voice your concern or outrage at a particular issue by taking it to your local MP or signing a petitition, or some other legal recourse.
Getting caught up with some amateurish scriptkiddie legion of dumb and dumber is just going to end bad ... you might get a cake ... but you probably won't get to eat it.
These people as a group have caused some serious disruption ... somebody will have to pay.
Watch as somebody's parents ending losing their houses as a result of the legal battle.
If your a parent worried about what your kids are doing on your family computer get some advice from a computer expert ... install some software to restrict certain activities ... question (in a positive way) your kids about what they are doing on the computer.
Topics like this should be discussed with your children.
Consequences can be aweful.
