First Amendment rights are not absolute. There are time, place and manner limitations. I don't know what the issue was here. If the reporters were interfering with the cops during their jobs, they could legitimately be arrested.
There was a news lawsuit in Tampa about 30 years ago. A construction worker had been backed over by a cement truck. The cameraman was trying to film the worker’s flattened body and a cop stopped him. As I recall, the cops lost that one.
At that time, I doubt that the network would have aired the footage. Today, probably it would hit Twitter before it even got back to the editor.
They were told to move and they didnt...guy just kept talking.....
