A man from Portland Oregon is suing police for unlawful seizure with excessive force after officers fired a Taser and bean bag rounds at him when he refused to stop filming a warrantless search of his neighbour's property last year.According to a report in The Oregonian, Frank Waterhouse claims that on May 27, 2006 he was brutally assaulted by police when officers followed a sniffer dog onto the property in pursuit of a fleeing suspect.Waterhouse says that the dog keyed on a car, prompting officers to break out a window which upset residents who maintain that no one ran onto the property. It was at that point that an angry resident grabbed a video camera and started to film the police search.The Oregonian report states:When one woman was told to stop recording, she gave the video camera to Waterhouse. He walked to the edge of the property, climbed up a dirt embankment and continued to record. At one point, he yelled to his friend, "Yes, I got it all on film. They had no right to come on this property."He says in the suit that police immediately came after him, and yelled at him "put it down." Officers moved towards him, and he said, "Don't come after me." Waterhouse said seconds later he was shot with a bean bag gun and a Taser and fell to the ground.
