"224. It is rightly pointed out by the Jan Sangharsh Manch that there was no prior information with the police and the authorities at Gandhinagar regarding the return journey of the Karsevaks from Ayodhya as can be gathered from the evidence of Mahobatsinh Zala (W-17), Raju Bhargav (W-31), DGP K.A. Chakravarti, Addl. DGP R.B. Shreekumar (W-995) and Ashok Narayanan, Chief Secretary, Home Department (W-994). Under the circumstances prevailing then, movements of Karsevaks was not a matter of concern. That appears to be the reason, why the police had not thought it necessary to keep itself informed about (171) their movements."
