республикански конвенционное

Несколько десятков организованных хулиганов, называвших себя анархистами, резвились подальше от антивоенной демонстрации ~10 тыс человек, наверно, опасаясь гражданского ареста.  И, естественно, их действия были приплюсованы к мирным демонстрантам, а в итоге появляются статьи о беспорядках протестующих:
4 Journalists Arrested as Minneapolis Protests Turn Violent

"Protesters, many who were dressed all in black and covered their faces with bandanas or gas masks, broke windows, tipped over newspaper boxes, pulled trash bins into the street, threw bottles, bent rearview mirrors on a bus, flattened tires, and attempted to block intersections by joining hands."

"Delegate Rob Simmons told the station that a group of protesters came toward his delegation and tried to rip the credentials off their necks and sprayed them with a toxic substance that burned their eyes and stained their clothes."

"At one point, people pushed a trash bin filled with trash and threw garbage in the streets and at cars. They also took down orange detour road signs. One of them used a screwdriver to puncture the back tire of a limousine waiting at an intersection and threw a wooden board at the vehicle, denting its side. Another hurled a glass bottle at a charter bus that had stopped at an intersection. The bottle smashed into pieces but didn't appear to damage the bus."

"Terry Butts, a former Alabama Supreme Court justice who is a convention delegate, was on a bus taking delegates to the arena when a brick through the window sprayed glass on him and two others. Butts said he wasn't hurt.  "It just left us a little shaken," he said. "It was sort of a frightening moment because it could have been a bomb or a Molotov cocktail."

Даже скучно, до чего всё примитивно.  С другой стороны, если проверенные средства действуют, то к чему изобретать что-то новенькое.  Организуй провокацию, замарай репутацию.  Учли уроки прошлой конвенции  2004 в Нью-Йорке.  Ну, и любопытным журналистам заодно досталось несмотря на их ба-а-альшие аккредитации.
