It appears that the government is non-existent and there is no rule of law," Hooda, the former chief minister, said.             Further commenting on the Nuh incident, Hooda said, "When the mafia is working on this scale and has no fear, it is clear that it has got patronage."                 Tauru DSP Surendra Singh had signalled a dumper-truck to halt to check documents. But the driver sped on, running over him. The officer"s gunman and his driver jumped aside to safety, but the DSP was hit.
