It's a situation we took very seriously. We had already taken several steps before it happened. I would say that we were ready for just about any situation.
I'll let the Sergeant-at-Arms speak so he can explain exactly what we did in detail. Much of this information is still being studied in camera, away from the public.
I'll let the Sergeant speak, as he will be able to provide more details, to a certain extent. It may also be a conversation that we will have to continue a little later.
