So we can agree that Postal was the source of the balcony report before moving on to something that has been discussed a million times already? Postal knew the president had been assassinated a short distance away. Police cars are flying up and down the road right in front of her. A man is observed by her and Brewer appearing to hide from the police by ducking away from the street whenever a police car goes by. He enters her theatre without buying a ticket (a crime). She simply reports a person acting suspiciously under the totality of circumstances. She has no idea whether this is the person the police are looking for or not. Just that he is behaving like someone trying to hide from the police. Which, of course, was exactly what he was doing. There is no great mystery here.
No, we can't. The dispatcher logs EVERY call, thus, it should be easy to show who did call, but you can't. Why is that?
4 miles is NOT a short distance. Neither one of them were trained or qualified to judge what was suspicious behavior. Furthermore, as we have seen in this thread there is serious doubt that either of them even saw the man as claimed.
