'As long as civilians are armed, I think that police officers probably need to be armed also.'
There we have it I'm afraid. Shoot-out at the OK Corral.

I suppose I'd be very afraid as an unarmed US police officer confronting an armed felon. I don't think actually there's any way back from this 'everyone can carry a gun' situation. Either they all disarm, or they continue firing at each other at the least provocation out of fear.

I had quite a lot of contact with the Deaf Association in Norwich as I learned BSL (British Sign Language) The deaf people I met were, of course, very dignified and determined to carry on their lives as normally as possible. I don't feel that being labelled in one's car as DEAF would necessarily be acceptable. But there are stickers, plates and so on to buy. They aren't however mandatory in the UK.
