Asymmetrical Information

I'm fascinated by this WaPo

I'm fascinated by this WaPo editorial calling for a gun ban, because it doesn't allege any actual harm has been caused by carrying a guns -- it simply assumes that the harm is obvious, without bothering to back it up with facts. The only safety incident they could come up with is that someone left a gun in a restaurant 3 years ago. Since I'm assuming that if anyone had been actually harmed by the gun carrying, they would have noted this, this amounts to saying that people shouldn't carry guns because the Washington Post doesn't like them. Well, if you're a regular reader you know what I think of that argument.
