Damn right too!
There was also a load of comments coming from the US mostly telling us that we needed to be armed because if we were these things wouldn't happen then. It misses the point though that in these terrorist type situations just carrying a weapon isn't good enough one has to be trained to use it in these situations. Being able to shoot at a range isn't good enough I'm afraid. Our police and Spec Forces train specifically for these situations, I'm sure they do in the US as well, close to me we have a FIBUA training facility ( Fighting in Built Up Areas) where the police and military alike train. I'm not saying don't carry weapons ( though in the UK you'll find few who want to) I am saying that in terrorist type situations it's a different kettle of fish compared to a robbery or burglary. Our troops a while back were patrolling streets in Northern Ireland where a lot of the people had weapons, shooting back when shot at had connotations because people were in the way sometimes deliberately so. Knowing when and where to shoot as well as being able to shoot quickly enough takes training.
I agree training is very important.
But if you are in a room and a barge is gonna barge in and try to kill you having a weapon even if you a poorly trained with it is better than being unarmed. It might only increase your chances slightly....but a little is better than none. That is a lot of our mentality on it.
