There are people who do such vile things in this country and are jailed for a decade or two. Perhaps released for good behaviour a bit earlier.
Afaik CP was stopped amongst other reasons because there were a number of errors made and innocent people being convicted.
But these days with DNA proof or cases where it is on cctv /phone messages or has been admitted (thinking of Emma Tustin)
Would it not make a good deterrent? Even if one person is saved from being murdered...
I appreciate that in the USA people still commit murder, but they also have guns there which means a higher incidence of spur of the moment violence.
But a sustained campaign of abuse - would such an abuser as Tustin have been put off if CP was an option, even if very rarely used?
It's easy for me to say that I would be deterred, but I'm not a psychopathic and sadistic person so the issue is, it's hard to say if people like that would be put off such a crime. Perhaps it doesn't even enter their heads that it's wrong.
