Stephen Clarke was arrested for allegedly photographing a sewer grate in Manchester. Then, when police found no photos of said grate on his phone they re-arrested him on suspicion of "being concerned with the commission of a terrorist act," held him for two days and searched his house and laptop. They subsequently released him without charge. They still have his DNA and fingerprints, of course, because our government has yet to do anything about the European Court of Human Rights ruling that states that the DNA should be destroyed.
Welcome to Britain. Yes, you’re fucked.
