logs may incriminate you even your own country protects you. think e.g. panama-leaks or other stuff that an activist or journalist might come across in your research ... also can you trust your own law enforcement not to be corrupt? how about if you know things connected to organized crime, ... in that case if you're based in the same jurisdiction as the mobster and e.g. you stole a couple of gig worth of incriminating material would you go to the police? it's pretty clear that you wouldn't want any logs.
I live in a country where the highest ranking politicians are fully in the hands of the mob. here a speeding ticket can be solved with a small "tip". Word of advise: don't ever trust the state to protect you. Also don't ever talk to cops no matter where in the world you're living (even less so if you're not guilty! this is first advise every lawyer will give you too).
