Are there not ways to try and make them not pick you?
Definitely, if you know what they are.
A lawyer once told me that lawyers, in general, don't like jury members to be trained in the law - so maybe walk in with some law books under the arm ?
That's one of them. I know because I worked as a secretary in legal offices for years, and even that status would have got me off jury duty because, inevitably, we do pick up quite a bit of legal stuff as well as having knowledge of a considerable number of local clients. Written evidence would be needed though.
You could try saying you knew the accused, or one of the witnesses, or even plead health reasons - mental ones in particular - but again written confirmation of the latter by a doctor would be required (palms can always be greased here.
Seriously though, won't your own occupation be regarded as a sufficient reason for being excused? That certainly applies to health professionals on the grounds that their absence, especially if a case dragged on for days, would be detrimental to the public interest. How quickly, for example, could a doctor be replaced by a locum? And nursing staff are pushed to the limit as it is. So surely the same thing applies to you?
When asked about anything just say "I don't care, just pick the quickest option I want to go home and watch Andy Murray". They won't pick you if you are not going to make an informed decision.
Saying she's a fanatical Andy Murray supporter would be enough to classify her as a raving nutter!
