IMO, we all need to regulate our behavior in one way or the other when we are out in public. That is what adults do. It applies when we meet with a non-LEO or LEO's both. It certainly applies since most of us would like to get rid of most gun laws such that just about everyone we come in contact with would have and/or carry arms. Talking about cards for the deaf and other behavioral things we could to do minimize the chance for a bad outcome doesn't mean we think we are likely to get shot, it just means we want to bring the chance of a misunderstanding down as close to zero as possible.
