In the last two months, at least 10 journalists have been arrested while covering protests in St. Louis, leading to multiple press advocacy groups to call on Mayor Lyda Krewson to launch an investigation into the conduct of the police department.
The National Press Photographers Association Committee to Protect Journalists drafted the letter to the Mayor Krewson, asking that an investigation into individual officer conduct be initiated and that increased training on the rights of press and how to properly deal with their presence be considered. The letter was prompted after NPPA member Daniel Shular and Journalist Amina Ali were arrested on October 3, during which Shular did not hear an order to disperse, but was still arrested after showing his credential and was never told he was under arrest or Mirandized, according to his lawyer. They were detained for 18 hours. The NPPA report says that journalists among the approximately 10 arrested in the past two months have alleged that they were "pepper-sprayed, cursed at, and treated with excessive force by police officers. Journalists were arrested even if they identified themselves and showed press credentials."
Of course, if found to be true, the allegations would represent serious violations of the First Amendment. The letter was cosigned by numerous press advocacy groups and was also sent to the Chief of Police and city counselor. You can read the full letter here.
