Remember, it's not only that they didn't have/refuse to share their footage. ATF actively disabled the man's own cameras.
If you heard banging out front at oh-dark-hundred, checked your Ring and it had been covered/disabled, what would your reaction be?
ETA: Also remember: This was a SEARCH WARRANT. They didn't even have permission to arrest him. If they were going to kick down the door anyway, they could have just waited till he was at work, then served him the paperwork at the airport 30sec before the searchers kicked down the door and entered a safe, empty house. The ATF deliberately chose the most violent, most likely to end in a gunfight way to serve this warrant.
