Where will the buck stop now, Mr Chidambaram?

After more than 75 Central Reserve Police Force (CRPF) troopers were killed in one of the most deadly attacks by Maoists in the thickly forested area of Chhattisgarh's violence-hit Bastar region on Tuesday, Home Minister P Chidambaram is understandably ` deeply shocked'. "Something has gone very wrong," he told reporters soon after the attack.

Yes, something has gone awfully gone wrong. Here is a list, Mr Home Minister:

For an attack of such a large scale, the Maoists must have planned for days, if not weeks. What was the intelligence wing of internal security doing in Delhi? Why were the signals not picked up? It is not as if the Maoists had laid the mines overnight.

Reports indicate that the CRPF convoy walked into a trap. Now, this is an old trick of the Maoists. The Naxalites usually send out tip-offs backed by proof of their camps, enticing the security personnel to take a particular route. This was commonly done by the Naxalites in Andhra Pradesh till the Grey Hounds set up to tackle the Naxalite menace found a way out. The Grey Hounds either delayed their trip or invariably took another route. Why was this not done here?

Why did the convoy not have a mine sweeper especially when the Maoists had launched deadly attacks barely 24 hours before?

There were reports that India has highly sensitive `eyes' in the skies that could pick up signatures of unusual moments of people in sensitive areas both in daytime and at night. Were these signals not picked up?

There were reports of India acquiring UAVs (Unmanned Aerial Vehicles) from Israel to conduct air surveys in sensitive areas. What has happened to this move?
