I'm sure that your many years in law enforcement make you an expert, but here's something you obviously forgot. When you are serving arrest AND search warrants at a location, you don't wait to arrest people AWAY FROM the area you want to search. It's too easy for a co-conspirator or even a friend to hear about the arrest, go to the loaction, and destroy or remove evidence. Second issue, there was a valid arrest warrant to be served - you don't have to be convicted to be arrested. (Let me know if that complex concept confuses you. Arrest does not require a conviction.) Last issue, an ERT is called in on any situation where it is deemed appropriate by leadership. That could be anything from an armed barricaded suspect with hostages to something as mundane as traffic control at the County Fair. You people really need to get over this. It was very unfortunate, it should not have happened, but it DID happen. Hopefully, we learn from it.
