Somewhat related, for a little sense of perspective. I studied E/E in Northern Ireland in the early 90's. I was regularly stopped by armed British Soldiers and searched. Invariably I have some half finished project in my bag. Could easily be passed off as bomb material. All it took was a simple explanation and I was on my way in 5 minutes.
