Brummie -
I'm with you here.....
#1 - if the Crown Prosecution is anything like our system, the courts are clogged, the prosecutor has too many cases, and the defense atty takes advantage and manages to delay the case multiple times and the court lets him/her do it. At least here in the US that delay caused by the defense doesn't count against the state, and we can still proceed with a case beyond the "statute of limitations" for that kind of reason, but if he's done as much time in jail as he would have if convicted, he gets out here too.
2 & 3. I see the "too lenient" sentence here all the time for these kinds of cases, even when the driver at fault is drunk!!! Makes me bonkers!

Course sometimes its impossible to convince a jury of the fault....having picked a number of juries it still surprises me sometimes that as a group of citizens they let people off that clearly were in the wrong criminally - it just takes one juror to tip the scales in the defendant's direction, whereas I have to have all of them agree to get a conviction. Course, I won't talk about the sentencing judges.......

All done!
