Bernd Kahre, spokesman for Herford court in northwestern Germany where judge Helmut Knoener works, told Reuters the 62-year-old wanted to make a stand against the current practice of prosecuting speeders. He said Knoener believed speed controls were not conducted to ensure greater road safety, but rather to provide the cash-strapped state with an additional source of income.

Knoener sees no legal justification for using photos in speeding-related court cases and is calling for clearer regulations about how, when and where speed controls can be conducted. But the speeders who think they've got off scot free may be in for a shock yet — the Public Prosecution Service can still appeal the sentences, Kahre said.
