In 2007, Simon Glik was walking past the Boston Common and saw three policemen forcefully arresting a young man. He took out his mobile phone and filmed the arrest. The police then arrested him and confiscated his phone. After the Boston Police Department refused to investigate his complaint against the officers, Glik sued the city. Three months ago, the US Court of Appeal finally upheld his suit.

Last year, National Guard sergeant Anthony Graber was pulled over for traffic offences by a plain clothes Maryland policeman. He filmed the encounter and posted it on YouTube, after which he was arrested, his property searched and electronic equipment confiscated. He was arraigned on charges for which he faced 16 years in prison. A Maryland court threw out all but the traffic offences.
