I did it last year. First day, not picked - very boring. Then on a drugs case for a week... ended up as Foreman. The evidence was overwhelming but one juror "couldn't ever find someone guilty unless they saw them do it with their own eyes". Another felt sorry for the criminal because they'd had "a hard life" - but not the victims, strangely enough. Second case was GBH. Nowadays, they only use expensive Crown Courts for serious cases we were told. Quite enjoyed the court "action" but wasn't eligible for any financial recompense (i.e. lost wages etc) apart from the miniscule lunch allowance and travel expenses they offer nowadays...so glad I only did 2 weeks.
The most interesting thing was going down for a potential case to have to declare I knew the defendant (unusual surname and I taught him as a 10 year old nearly 30 years ago
)... that ended up being a 3 month case, I read - multiple sex attacks at a variety of workplaces.
My 20 something daughter was on a multiple rape case in Manchester the other year and found it all very harrowing (understandably).
