I know how search warrants work. I'm not an idiot.
I wasn't questioning their right to do that, I was questioning its necessity. They serve the warrant at a time when the resident is very likely to be gone (being a working man), and big surprise, he isn't there. Why not serve the warrant in the early morning before he's left for work? Why not call him to open up the house, he's a public figure and surely quite easy to find? They have control of the premises, executing a warrant isn't a time-sensitive task under those conditions. Indeed, if they really believed time was of the essence, why give him the morning to destroy evidence? No, the only reason you show up when you know the owner isn't there and then proceed to bash down his door is because you're making a statement.
This is my feeling to. There was no real need to do it as they did unless they WANTED to do it when he wasn't around so they didn't have to be accountable for what they did when nobody was watching. In fact when he did show up they made him wait outside which seems very wrong. You have a right to be present when your things are being searched.
