Thrashing Modi government over Pulwama assault, West Bengal boss pastor Mamata Banerjee on Monday asked the Center for what good reason it overlooked insight reports and let the CRPF guard go through the region where the assault occurred.

"For what reason did the Center not successfully prevent Pakistanis from completing such assaults in every one of these years. Just when a race is thumping at the entryway, you consider beginning a shadow war?" she inquired.
