According the Home Minister, the Maoists had killed the civilians mostly by leveling them as 'police informers.'
"As long as the principal left wing extremist organisation was not challenged effectively, it expanded its area of activity, areas and targeted the security forces as well as civilians," said Chidambaram.
"In 2009, 591 civilians were killed, of which 211 were named as police informers. This trend has continued in the first half of 2010 too, with 325 civilians killed, of which 142 were named as police informers," said Chidambaram in a meeting in New Delhi on Jul 14.
He said the central government was concerned that ordinary citizens were labeled as police informers and killed by the CPI-Maoist.
"The CPI-Maoist has no right to set itself up as judge, jury and executioner. In fact, it has no right to carry arms. It is a banned organisation and functions outside the pale of the law," claimed Chidambaram.
