We don't have the death penalty for murder in this country, nor have we since 1969.
There are actually still at least three crimes for which the death penalty is possible in the UK, Piracy on the high seas, High treason, and Blasphemous Libel, as well as a number of statues which although no longer recognised, are, as yet, not repealed.
For instance in the town statutes of some northern English towns, it is the duty of all townsmen to shoot dead any Scotsman in town after dark, with a Longbow.
However that being said, I have never agreed with the death penalty, it always seemed like judicial revenge, rather than a punishment, and there have been many cases where the conviction was unsound, leading to an innocent victim being killed for a crime they did not commit.
What baffles me most about the cumbria shootings, is that there appears no motive for them, no pattern, and no sense, this does not appear to be a case of an evil premeditated shooting spree.
What continues to bother me is, where the hell does a 52 year old taxi driver get a firearm and enough ammunition to do something like this?
