That's correct, I believe it shouldn't be illegal to know anything. Nor do I think science needs any kind of regulation.

Hurting people, lying, that's already illegal.

I think Maybe you misunderstood my argument. My argument isn't that good guy with a voice cloaner is the only thing that can stop a bad guy with a voice cloaner. That's, as you pointed out, stupid. My argument is that no one benefits if how easy it is to make one remains a secret to everyone but the bad guys.
