An awful lot of tools provide the opportunity for their users to break the law, and yet we still sell those tools and place the onus of following the law on the users. While guns are the obvious example, lockpicks are widely and freely available, as are a whole host of other items with which one could commit nefarious deeds.

Copyright law seems to be one of the only areas in which the fact that someone Could use a tool to commit a crime seems to be grounds for criminalizing the tool and not the act.
