THIS IS NOT JUSTICE.
The British had absolutely the right sense of things. A quick trial, a quick appeal, to be quickly followed by a swift execution. This, and ONLY this, has been PROVEN to be a complete and total deterrent to violent crime.
The Brits? So did "we", at one time. The classic case, the fellow who tried to shoot president-elect Roosevelt in 1932. He did shoot Mayor "Tony" Cermak, of Chicago, who lingered for a couple weeks before dying. The perp was tried and convicted, midstream for murder, and sentenced to death, executed - in less than a month.
