Photo: DPAHamburg has drafted in some 20,000 police to protect against terrorist attacks and street violence at the G20 summit, with the city police force describing it as the biggest operation the city has ever seen. Most are expected to be peaceful, but some, with mottos such as "Shut Down G20" and "G20 - Welcome to Hell", are considered likely to escalate. "It will be the biggest operation in the history of Hamburg's police," said the city-state's police spokesman Timo Zell.
