I know what interview you're talking about. He tried to make it all sound dramatic and made sound effects and stuff like he whipped the gun out and shot her like he was badass. He was obviously pleased as punch to be the center of attention for once. An investigator said that she was shot at an angle, as if she were bending over slightly and the gun was below her (not pointed straight at her like Bardo claimed). The guy said Bardo was making up the whole whipping out the gun thing and they think he had the gun in a bag and act liked he was rummaging around in his bag to get her a card or something and then shot her. Bardo did say she got pissy with him but who wouldn't? Some strange, early man looking dude coming to your apartment and bugging you before you have to go to work? I'd be pissed and "whiny" too.
Bardo's whole claim was he tracked her down because she had become a "Hollywood whore" and he was going to punish her because she was in that film Scenes from a Class Struggle where she appeared in bed with Ray Sharkey. So yeah, dude wasn't "crazy" in my book. I mean, he's screwed up in the head for sure and isn't connected with reality but he knew what he did was wrong. Now he's linked with Rebecca forever which is what he probably wanted.
