Who killed Benazir Bhutto is likely to remain a question mark given the country’s past history relating to investigations into high profile killings or disasters of epic proportions. Sources in the crime investigation agencies revealed a disturbing fact that the Britain’s Scotland Yard probably won’t be able to pinpoint the killer or killers or the people who plotted her assassination. The British investigators are trying to reach a conclusion, based on circumstantial evidence and whatever remains of the physical evidence, on what caused her death and how it may have happened, these sources say. Beyond that doesn’t come under the purview of the British police, sources said. 
Commentators, analysts and politicians also point toward the fact that since independence, the nation has seen dozens of judicial or other commissions investigating high profile cases in Pakistan, none of which reached a conclusion. Starting from the assassination of first Prime Minister Liaquat Ali Khan in 1951, at the same Liaquat Bagh venue in Rawalpindi where Ms Bhutto was killed, to the killing of Murtaza Bhutto, high profile crime cases have remained shrouded in mystery. The first premier’s assassination is still a mystery, while the 1971 debacle of East Pakistan was investigated by a judicial commission and its report was made public after 29 years. Yet the report failed to lay the blame squarely while alleging the incompetence of the then dictator Yahya Khan as a cause for the downfall of Dhaka. The probes into plane crash that killed former military ruler Zia-ul-Haq in 1988 and the Ojheri camp blast in Rawalpindi the same year that killed more than 100 people haven’t seen the light of the day. Probe into Bhutto’s murder will be another file that will be shelved -- eventually. 
The initial investigations into Bhutto’s death have already been twisted and tainted so much that people have lost confidence that there would be any acceptable conclusion that the Pakistani or foreign detectives will reach. First of all, the police have washed away all the physical evidence from the scene of crime at Liaquat Bagh. Who ordered the cleaning of evidence and why? Why was police in a hurry to collect whatever they could gather from the scene and not cordon off the area for further investigations? People walked in and out of the crime scene without any hindrance. Why was the Interior Ministry spokesperson Javed Iqbal Cheema in a hurry to rule out the possibility that a bullet-wound killed her? What prompted him to claim that Taliban commander Baitullah Meshud was behind her killing? The PPP has rejected Cheema’s claim of Meshud’s involvement while also discarding the investigations that she was killed by hitting her head on the lever of the car’s sunroof. The reason of her death, as given by Cheema, was so absurd that Pervez Musharraf a few days later had to admit that she might have been killed by a bullet.
Cheema’s story detailing the cause of Bhutto’s death has not done any good to the government’s investigations. Now no one is ready to trust the government’s investigations. People have just lost faith in what is said by the government, which has already lost its credibility in the eyes of the people. Cheema had said that it wasn’t a bullet that hit Bhutto and neither the death was caused by the bomb explosion. He said the death was caused from a wound inflicted by the lever of car’s sunroof, which pierced her temple when she ducked soon after the explosion. Although he produced a video footage of the incident where it showed a handgun, close to Bhutto and three shots were fired at her before the explosion, he claimed the gunshots missed her. Meanwhile, a local newspaper has reported that initial investigations showed that Bhutto was hit in the head by a bullet. The report also gives details of the bullet and the handgun and it also provides minutest details of such as the distance between the killer and Bhutto. 
While television channels got hold of other video footages of the incident, the most startling footage came a week later, which showed Bhutto’s most confidante servant and person introduced by her husband Asif Ali Zardari making strange and incomprehensible gestures at the stage while Bhutto was addressing the rally.
The footage gives another twist to the investigations. The Pulse has that complete footage, which shows the servant, standing next to Bhutto on stage, making hand movements like slitting the throat and then moving his eyes as if pointing towards Ms Bhutto making the speech. The servant also looks very restless and continues doing it for a while. Though the person in question has denied any involvement but he has also, in interviews to newspapers, failed to give any plausible reasons for acting in such a strange manner. Certainly, the investigators would have got hold of that footage as well and will probably question him.
Musharraf’s claims that Mehsud was behind Bhutto’s killing, based on the recorded conversation between Mehsud and his aide and provided by the intelligence agencies, also lacks credibility given the uncountable loopholes in the so-claimed intercepted phone call. Besides Maulvi Omer, a spokesperson for Mehsud, denying the role of Mehsud in the killing of Ms Bhutto there is no way to prove, from the recorded conversation that the intelligence agencies have got Mehsud on one side of the phone line and that he is talking about killing of Ms Bhutto.
The PPP has already said that a probe by Scotland Yard won’t be fruitful because its hands will be tied up, as it will be working under the government’s instructions. The party leadership is demanding that the government writes to the United Nations for the investigations similar to the one held in case of Lebanese leader Rafiq Harriri’s assassination. The PPP is also continuing to insist that Bhutto’s letter to her American friend Mark Siegel, which was meant for CNN anchor Wolf Blitzer, be regarded as her dying statement and be used as evidence in the probe. In that letter, published by Dawn newspaper, Bhutto on October 26, a week after an attack on her in Karachi, had written that Musharraf be held responsible for her death.
The Scotland Yard Team visited FIA headquarters on Tuesday. The Scotland Yard Team was formally briefed by Special Investigation Group (SIG) on some of the proofs and evidences relating to the assassination of former Prime Minister Benazir Bhutto.
The Scotland Team during their visit to the FIA headquarters also held talks with DP FIA Tariq Pervaiz and discussed with him the ongoing investigations so far done in Benazir's case.
On the occasion, Special Investigation Group (SIG) repeated the Crime Scene of Liaquat Bagh and briefed the Scotland Team about different aspects related to it. The Scotland Yard team remained at the FIA Headquarters for almost three hours and were seen busy in collecting evidences.
On the other hand, the spokesman for interior ministry, Brig (R) Javed Iqbal Cheema has said that the visiting team of Scotland Yard was free to investigate the murder of Benazir Bhutto.
Addressing his weekly briefings at the ministry on Tuesday, he said that all earnestly awaited their findings, and announced that they had recently also met with President Musharraf, during which they have expressed their great gratitude for independent investigations, while President Musharraf has also acknowledged thanks on behalf of British government for its cooperation.
He hoped that any kind of assumptions would not be nurtured until the investigations are completed, assuring that the visiting Scotland Yard team includes all kinds of experts, who were examining all kinds of available evidence.
Cheema also expressed his deep hopes that masses would fully cooperate with government in maintaining peace during Muharram, citing strict security measures for all Imambargahs and mourning processions.
He said that important directives have been passed over to all the provincial governments and security measures have been beefed up at sensitive points, declaring 35 nationwide districts under special vigilance. 
Given the controversies surrounding the whole issue and to satisfy the family and supporters of the victim, there is no harm in ordering an independent inquiry into the incident. If Musharraf and the government thinks and they are convinced that their hands are clean, then there should be no delay in keeping the inquiry controversy-free and to take all steps that will ensure that the PPP is satisfied with the probe. Another debacle, disaster in the country’s history cannot be allowed to be shelved without any conclusion.
