It's up to the user to prove that the child porn isn't on his computer. As someone pointed out earlier, you could just download a bunch of child porn with a tor exit node running on your computer and say it was someone else.

You're abandoning central pillars of modern law here, namely the presumption of innocence as well as the right not to incriminate oneself.

No, not exactly. Perhaps I didn't word it correctly. A crime has been committed using the user's internet connection, so in most civilized countries (i.e. places I would like to live in), that means the police have the legal and moral right to investigate that crime. Until proven otherwise, the 'tor' user is a suspect - watch a few episodes of CSI if you want to get a rough idea how it works.
