AP:
At some point, sheriff's deputies who heard reports of the ambulance responding to an accident at the ranch stop at the front gate to see if anyone needs help, but are told no one needs assistance. The Secret Service earlier had said the deputies were seeking to interview Cheney, but on Tuesday they said that was not the case.

Before anyone (ahembeam me up scottiecough) starts with the sarcasm on me, I'm not saying I believe one way or the other. I'm just saying this is the evidence available. If the SS and the Sherrif both say that nobody was refused entry (and I'm not sure what the Sherrif says) then nobody can say it happened. The first time the SS was quoted they COULD have got it wrong.
