If the feds came to the cops in your hometown and said “We need some help with this “no knock” warrant.” Do you think they’d say “Nah, can’t help you. We’re for the people.”
I think they’d say “What can we do to help?” without even looking at the warrant. Then they’d be all giddy saying “Yippee! We get to put on our military gear and play soldier!”
Maybe in some circumstances. I was in the biz for years and believe me read every warrant I went on to assist.
