We think we are safe, when law enforcement cross our paths, but it's not true for everyone. Every organization has their bad apples, and you are just lucky, if your path do not cross
one of them. One or two bad apples, do not spoil the whole basket... Our local police force, also has some bad apples, but the majority are good people, with good intentions.
It's sad to see what people will do for money. Unfortunately no amount of improvements on the money system will solve this. No matter if we are trading goods, gold, fiat paper or Bitcoin, people will still do evil things for money. We need improvement in human soul and not only in the actual system in which money works. It's disgusting to hear he will torture people to get some sad BTCs and it's even more frustrating when he is supposedly an FBI guy.
