No, the purpose of a search warrant is to get legal permission to search private property. A no-knock warrent is what you are referring to which in fact they did have. They could have arrested that Glover guy, maybe kick the door down where he was, but I see no reason they couldnt have used a little more discretion on the other locations. Knock, identify yourself, and then if they don't let you in, go for it. As I said, it would be a matter of minutes and any meaningful amount of narcotics can't be destroyed. Plus cash. Plus guns.
You can bet LE and judges nationwide will be examining the process/requirement for these types of warrants going forward. Even if they thought the guy was in there, he's not getting away. In this case however they knew he wasn't.
