The things I always wonder about TOR: Won't I look like someone else's computer? Is it possible for me to get in trouble for because someone else's traffic exits from my home network?
You can chose whether or not to be an exit node, so nobody else's traffic will exit through your connection if you don't want it to.
If you do enable it, my presumption is that by demonstrating that you have tor running you can show that traffic from your connection is as likely to not be you as to be you - but I'm not sure if this is backed up by law, or has been tested in court.
They are a part of the DMCA that protects internet service providers who transfer illegal data with an automatic protocol. I think the intended case was to protect ISP so they would not need to police their network.
Mind providing a link? I briefly looked at Tor's FAQ and couldn't find anything on that.
Also, a business entity wouldn't help in the chance of criminal investigation, which means the money spent creating a business entity would be for naught.
Thanks for the link. It is only in the circumstances of running an exit node. If you aren't running one, then you don't need to worry (as stated by several others already).
In addition to what other posters wrote: you can decide to run an exit node but restrict the sites that are available to Tor users. The most obvious use is to disallow your home country. For extra safety restrict it to far away countries that have no legal power where you live.
