Didn't one of the major ISPs get their ass handed to them in court for trying to say that they were somehow exempt from keeping exactly this sort of information? I mean, you can SAY it, but it would be sort of insane to make a statement like that without a lawyer signing off on it. The law doesn't have a "this is too hard for us" or "we didn't build our network for this" exemption, does it?
