I was peeved that he might be a police officer, so I followed him to the gate, which was slow to open, and I said "I hope you're not a police officer." He replied "Why?" I said "Because you've just deliberately ridden through a red light." To my surprise, he replied "It's a bike, it doesn't apply." I said "It does, the Road Traffic Act applies to cyclists." to my further surprise he simply said "It doesn't matter." He then rode off into the compound.
Now, it was about half an hour before the normal 2pm start of an afternoon shift, he had the build of a police officer, and was in his 40s with greying hair. So, unlikely to be a probationer. OK, he could have been civilian staff, perhaps a call handler, or a cleaner. I have my opinion as to what he was, but I doubt the forum net nanny would allow me to say.
