I think that the death penalty should be brought back and strictly adhered to in cases where......
1. There is no doubt of the offenders guilt. ie an admission of guilt or evidence of total guilt in a crime in which some innocent party has died through being attacked without provocation.
If they lie about being the one who did it, tough ****.
2. If somebody commits a crime where another loses his /her life through an attack involving a gun or any weapon. Don`t carry guns or knives, its against the law.

3. Anyone caught sexually abusing a child, And Rapists.
4. Anyone who kills a member of the police force.
5. They should also bring back the charge of Treason. Again, punishable by Death.
6. An attack on any member of the royal family should be punished by a life sentence.
I`m sure i can, realistically think of some more but the above one`s are the ones that concern me.
Lets get back to decent Human values and morals. Don`t steal and have respect for yourself and others.
Go on........... Pull it to pieces now with the Human rights act etc, etc.
