Hello Englishman,
I worked in the Crown Courts of the UK for eight years as a court reporter, shorthand writer, including the Old Bailey and now I work in the US courts and I can tell you that there are quite a lot of differences.
In the UK I did mainly criminal cases; I was one of the team of court reporters that worked on the Rosemary West trial in Winchester back in 1994. That was an experience. I also had a few celeb trials, including the Freddie Starr case where his gardener was accused of stealing from him. He was found guilty although he maintained that the items of jewelry were exchanged for sexual favours.( By the way, when he got out of prison after a year or so he moved right across the street from me in Reading!)
I also did the murder case with no body and the ex-policeman, Buckingham Palace guard that stalked and murdered his wife a few years back.
I also sat throught many sad child abuse cases and lots of fraud, including some of the Maxwell fiasco.
In my opinion, I think the British system is better than the US system as far as the proceedings goes. US courts can be more entertaining when it comes to a slinging match, and UK attorneys are much more polite. Plus, the hours are better. In the UK most judges roll into court around 10:30, whereas here in the US, 8:30 is standard.
There are stark differences when it comes to life sentences. Life in the UK is 14 years mandatory with the Home Office making the recommondation as to release, if ever.
In the US life can mean anything from 50 to 300 plus years. Some states also favour the death penalty. I happen to reside in one now at the moment.
Hope this answers some of your enquiries.
