Tuesday's blast targeting a bridge leading to the Indus river near Hyderabad cannot be dismissed as an isolated attempt at sabotage, as was implied by the police who said a mystery caller had claimed responsibility for the attack.
Luckily no damage was caused to the bridge nor anyone was hurt. It took the law enforcement agencies several hours before they located the site of the powerful blast which was heard for miles around the area.
Police said the mystery caller identified himself as an operative of Sindh National Liberation Front and threatened to target railway lines and trains if the government did not scrap plans to build the Kalabagh dam.
Hard as it may be to ascertain the truth of the caller's statement, the fact remains that a blast did take place and that law enforcement and intelligence agencies were caught unawares yet again.
We have time and again argued in these columns that it is the failure of the myriad intelligence agencies that leads to such acts of terrorism, regardless of who commits them when, where and for what reason.
A government that by its actions has embroiled itself in political controversies, and that has played an aggressive role in hunting down Al Qaeda terrorists without first evolving a consensus on either front, should have been prepared for a backlash of this kind.
Maintenance of law and order has now become a serious problem across the country - from Karachi and Sindh to Balochistan, Punjab, South Waziristan and the Northern Areas.
Terrorism, whether rooted in political antagonism towards state policies or in sectarian extremism, has been a fact of life in Pakistan since the early 1980s, but its manifestations have never been this menacing and widespread as they are today.
And this time round, the military-led government cannot shift the blame onto intransigent politicians as has been the practice in the past. Unless an inter-provincial consensus is evolved on sharing water and revenue equitably, as in the case of Punjab versus the rest, and the fruits of development, as in the case of Balochistan, the law and order situation will remain alarming.
Long wait for justice
In a very telling sign of the operational flaws inherent in the country's judicial system, Afzal Haider, who languished 17 years in jail without being convicted, was finally released after being acquitted of the charges against him.
While not all the details of the case are before us, judging by the nature of the crimes for which he was booked, it would not be wrong to assume that his time in jail without conviction could have exceeded the period of actual sentence had he been found guilty.
Whatever the case, Mr Haider's example is reflective of a nation-wide scourge whereby many of those behind bars for months and years have yet to stand trial. The existence of draconian laws like the Hudood Ordinances compounds the misery of the prisoners even more as they can be detained on the most unsubstantiated of charges.
This is wrong and should not be tolerated in any civilized society. It is not only individuals who suffer, their families, too, must undergo the trauma of long separation and the agony of undecided cases.
Obviously, the wheels of justice have to be better oiled to get going - an image that finds resonance in the few, ramshackle vehicles available to transport the detainees to court and back.
There was a proposal some years ago to have makeshift courts on jail premises to resolve undecided cases. Perhaps, this suggestion can be looked into, at least for those charged with minor faults.
Besides, not many are able to afford legal counsel - another reason for delay in disposal of cases. Small wonder our courts are overcrowded. It is time some major reforms were carried out to cut down law's delays, speed up the trial process and spare the detainees the agony and distress of long wait for justice.
