Only if obtained by correct process of law and you resist the temptation to "explain yourself" to the police.

You're forgetting that you aren't required to explain yourself in court (5th Ammendment). It's the job of the prosecution to connect the dots and prove you're guilty. Smart defendants hire their own expert to refute the testimony of of the prosecution's "expert".

As to Wikipedia, I think a random overwrite pattern would be way better than them finding fragments of the following (just two examples) :

http://en.wikipedia.org/wiki/Nuclear_weapon_design http://en.wikipedia.org/wiki/Child_prostitution

Practically every illegal act has an article on Wikipedia .. why deliberately "seed" your hard disk with them?
