So it was an example of excessive force. And it was done at night and was a no knock, so they must have shown in the warrant evidence of manaforts propensity for violence?
A Federal warrant may be served in daylight hours, beginning at 6am.
I did not read that this was a no-knock, anytime warrant. If it was, there was no reason to wait until 6 am.
The report is consistent with the service of a Federal Search warrant by federal authorities. They may well have been heavy-handed at the beginning, but that is the nature of controlling evidence sought as detailed in the warrant.
Not defending their actions, but commenting based on the report i read.
