A Swedish prisoner has been accused of deliberately farting near guards in a protest against his incarceration. The problem is so severe that he was served with an official warning that future flatulent conduct towards prison guards will be punished. I guess prisoners never attack guards with homemade weapons in Sweden. From the article: "Anders Eriksson, the prison's warden, realized that the inmate's repeated episodes of flatulence were 'a series of concerted attacks' on staff. 'I have worked within the prisons and probation service since 1986 and I have never experienced a situation where behavior of this sort has led to punishment,' he told Sweden's Metro newspaper."
