He said that instead of arrests of the killers to lodge FIR under section 147, 148 and 151 PPC to term this funeral procession an illegal assembly and breach of peace against the mourners of the funeral is barbaric act of the administration when teargas shelling on the women, elders and children have terrified the mourners and force them to think that they are not secure by the hands of terrorist nor by the government of Pakistan. Mr. Nazir S Bhatti demanded the immediate withdrawal of cases against 55 Christians arrested by Karachi police during the funeral procession and to stop raids on the houses of the Christians. He said that its duty of the administration to arrest the killers of seven innocent Christians but police is making raids and further arrests on the houses of Christians. He expressed his concern that police is making the only survivor of this incident Robin Piraditta, a suspect instead of making arrests of the culprits. He said that FIR of that sad incident may be made public and the police on duty in the vicinity may be named in the FIR on neglecting the safety of the inhabitant. Meanwhile the PCP correspondent have added that, A top psychiatrist on Wednesday poured cold water on a police theory that the survivor of the Sept 25th attack on a Christian charity was misleading investigators and concealing information from them. Prof S Haroon Ahmed of the Institute of Behavioural Sciences in Karachi sprang to the defence of Robin Piranditta who, he said, was probably suffering from post-traumatic stress disorder--a medical condition that causes involuntary confabulations in patients when a question is repeated over and over again. "I sympathies with Robin's ordeal...The truth eludes him because every time he is asked the same question. He fills the memory gaps by confabulations," Prof Ahmed said in a statement. Piranditta's condition is made worse by the "ignorance of investigators" whose reaction is based entirely on the premise that he is leading them down the garden path, according to the psychiatrist. Piranditta was the only worker from among nine Idara-e-Amn-o-Insaf staff who was not shot through the head by the assailants. He was, however, badly beaten up. Police sources say Piranditta is increasingly Being seen as a suspect in the shooting tragedy. Explaining the symptoms induced by post-traumatic stress disorder, Prof Ahmed said, "There is usually a Subjective sense of numbing and a patient loses full awareness of his surroundings." Also, he said the Patient suffers dissociative amnesia and forgets important aspects of the trauma. The condition can also induce imaginary ideas when one isn't able to recall events, he added. According to Prof Ahmed, the kind of stress that Piranditta is suffering from could last for up to four weeks. "This disturbance lasts a minimum two days and a maximum of four weeks." He advised the investigators not to read too much into the results of the polygraph tests that they made Piranditta take more than twice. "Lie-detectors do not deliver the truth. It only delivers when one knows how and when to use them," Prof Ahmed said.
