VIEWING the past four incidents of bomb blasts in Lahore, one tends to wonder whether the terrorists have changed their tactics and decided to use low-intensity explosive devices to hit their targets. The intention appears to be to create fear and not inflict casualties. Besides, in these cases, the urge to enforce, if needed with force, their version of puritanical Islam seems to be uppermost in their minds. These conclusions find conformation in last Friday's incidents (one on the premises of Alfalah Theatre on the Mall and the other at Tamaseel Theatre on Ferozepore Road near Mozang Chungi), November 22's near Alhamra complex at Qadhafi Stadium where the 25th World Performing Art Festival was in progress, and October 8's near fruit juice shops at Garhi Shahu considered by some dating rendezvous. The devices used did not kill anyone; only caused injuries to 13, none in the most recent. The buildings suffered damage and there was, inevitably, widespread sense of panic in the air and the feeling that life was not safe from the scourge. The fact is that barring a small minority in the country no one adheres to their view of the religion but even that section of the population could not claim immunity when public places are hit. It might be abstaining from theatres and films, wearing beard and regarding music as inciting baser feelings, but would hardly be favouring resort to force to convert the rest to their interpretation. The periodic terrorist acts should wake up the concerned authorities to the reality that all is not well in this part of the country and they have to be constantly on guard against an enemy that is hidden. Perhaps, the two persons arrested on the spot at Alfalah on Friday might provide a peep into the militants' network behind these blasts, but their mode of operation would demand sustained vigilance and full cooperation of the general public. No doubt, the phenomenon has deeper roots and to put an end to it would need a comprehensive approach that addresses their genuine grievances especially those with international implications. However, there is a lot that the government can do to improve the security situation. For instance, the streak of compulsion to enforce a particular, rigid view of the religion that symbolises peace for all mankind and tolerance has to be tackled through the spread of the true message of Islam. The religious leadership should take up the issue in all sincerity. Unless this idea of peaceful co-existence goes home, the menace would keep rankling the social fabric, not leaving sectarian harmony intact.
