An unfortunate update: A 29-year old man who was suspected to be a developer of Tornado Cash was arrested and detained in Amsterdam in the Netherlands. This followed after the US Treasury Department blacklisted the Ethereum mixer for being used for money laundering.

This is worrisome because the man, assuming he's indeed the developer of Tornado Cash, was just writing codes, codes that are never meant to help criminals. It was for privacy's sake. Privacy is a right. If his open source code was utilized by evil entities for evil purposes, is it his fault? Is he a criminal simply because somebody else took advantage of his neutral codes?

This is unfair and illogical. This line of reasoning would have the creators of the internet, smart phones, knives, and other neutral tools arrested for having their inventions used in crimes.
