Knife/any murders. is it time for capital punishment for those found guilty

[mtread]

Mtread there are far more innocent victims of murders that are released, than miscarriage's of justice. 

As I said, it's not a numbers game. If you're happy for an innocent person to get hanged as a deterrent to prevent someone else murdering again, then I hope the innocent person isn't one of yours.
You can release an innocent person, but you can't dig them up.
