The SS should not have been at the house in the first place.
I'm not familiar with Secret Service procedure. I'd imagine that they need to investigate all reported threats to the president. Would a phone interview be "harassment and intimidation"? Plenty of paranoid freepers would call it that. They'd complain about checking whatever this poor schmoe had on file, too.
I think that once the SS was contacted, they had little choice but to check things out. It was the fool that initiated this - and his commanders, or their procedures that allowed it to escalate - that need to be excoriated here.
Like I said, I'm not waiting on anything to happen. I'd be worried, though, if there was a *real* threat reported by OKC PD...How much credence do you think that they have, now?
