Investors sue Treasury Department for blacklisting crypto platform Tornado Cash
Banning a service because it "might be used for illegal purposes" is insufficient.  This is a problem with law enforcement in general: they are lazy and seek to have automated solutions to so much of what used to be called police work.  This applies to warrant-less wiretaps, pulling information on people from 3rd party data brokers to side-step warrant and FOIA requirements, and more.  I would rather money-launderers get away with things and for freedom to prosper than to have an all-encompassing surveillance state.
