[Trisquel-users] A few worries about Tor

[shiretoko]

Maybe it's completely absurd, but I wondered whether I can get in trouble for  
using tor, since traffic is directed to my pc and maybe this traffic contains  
illegal material.
So are there any justifiable worries about using tor?
Did anyone get sued / is it technically possibel?
I would like to use tor-browser-bundle.
