OK, so what is this "cybercrime"? Is it "cybercrime" for Chinese dissidents to criticize the government on Facebook? I'd say it is. You might end up as an involuntary organ donor. India also suppresses dissent, albeit not so harshly. And what about searching for gay porn in the UAE? Or dissing the King in Thailand? My point is that most of these people who go on about Tor and "cybercrime" are ignoring activities that are in fact illegal for about half of the world's population.
The way I think of it is like this. Tor is a tool. Like all tools, it can be used for right and wrong. A crow bar can also be used for right and wrong. Does that mean we should ban all crowbars? Of course not. All tools also leave a trace and this will assist Police in investigating crime.
I would say that depends upon who is using the tool, and whether or not a classic case of mis-direct would be considered a trace. A trace is actually a good thing for the user of the tool if that trace leads down a false trail or mis-directs the one in pursuit.
Sadly, the direction legislation is going in means that both bad-guys and the knowledgeable innocent (because of false positives), will be actively engaged in spreading chaff, and also, worryingly, fingering the innocent. Everything they do in regard of mass/bulk collection and storage and data mining makes this prospect an obvious end-point.
