The Sheriff's department tells a different side to the "police gassing reporters and dismantling their equipment" rhetoric. I haven't read if the reporters involved confirm or deny whether they gave consent for the officers to move their stuff.
Gov. Nixon gives police control of Ferguson situation to Missouri State Highway Patrol : News
"Over the last few days, the St. Charles County Regional SWAT Team has assisted in Ferguson at the request of the St. Louis County Police Department to help respond to looting and for protection of the property of Ferguson citizens and businesses. On Wednesday, August 13th, video footage was taken of St. Charles County SWAT officers handling media camera equipment. The position of the St. Charles County Sheriff’s Department is that the media has the right to cover these events and supports the freedom of the press, and the SWAT Team has not been any part of attempting to prevent media coverage. In fact, last night the SWAT Team officers were assisting the media in moving their camera equipment and media personnel to a safer area with their consent so that they could continue to cover the event. The Sheriff has notified St. Louis County Police that the St. Charles County Regional SWAT Team is available to protect life and property but does not have a continued role in crowd control during this time of civil protest."
