Should the bar for conviction be raised higher than it is now - yes.
Does more harm than good? Pray tell me sir, what dissuades immoral people from committing crimes? I grew up with criminals for relatives btw - including my father.
I curious as to what you believe.
Probably a lot of things including punishment, prison, and possibly death. But I think the record shows that CP hasn't really dissuaded people from CP crimes.
The focus of the state IMO, is to bring the whole penal code out of the dark ages, clean up the prisons, make prisoners productive and pay for their stay in the Big House, and fix the parole process so society is protected from dangerous criminals. IMO, false solutions like CP create an illusion of remedy while these real problems continue to go unresolved.
