Last time I was called for jury duty, I was relieved of a small Swiss Army pen knife and a pipe tool at the entrance of the courthouse. You'd be lucky to get a Bic pen past the security.
I was so ticked off that I began carrying the biggest Swiss Army knife they make--which is indeed a deadly weapon.
I too was relieved of my leatherman pocket tool for jury duty. I have seen videos of parents and grandparents of murdered and assaulted children being taken out by one shot in a lax court situation. I do hope for the best in these situations.
