All the care taker such as police ,CBI and inteligence are biased by our poiticians . Half of them are utilised by them and other half are busy with collecting "CHANDA " from vehicle ,poor shop keeper .They are more busy with this activity rather than security so this type of attack will continue and our politician will be busy for 2-3 days and in due course they will forget what was happened . Again one more will be there and same drama will continue and the show will go on like this . They are only bother about theer pockets not human beings those innocent peoples are given their life without their fault .
