Judges, prosecutors and police officials have to keep themselves constantly updated on developments in widening application of science and technology to check criminal minds using the ever expanding sphere of cyber space, Kerala Chief Minister V S Achuthanandan said. Inaugurating a southern regional workshop on `Cyber law: Issues and Challenges in Enforcement' here on Saturday, the Chief Minister said `intelligent criminals' would think and act ahead of others to stay in business. "The ever expanding sphere of cyber space has thrown up challenges and opportunities to the criminal minds. They outpace the barriers raised by technology and laws," he said. The Chief Minister thanked the Judges taking part in the workshop and hoped they would come up with suggestions for the government and the judiciary to put in place mechanisms to ensure that the justice delivery system could effectively cope with the new challenges before it. The workshop was organised by the State-run Centre for Development of Imaging Technology (C-DIT).
