Normality returns, but for how long?

The city of lights has finally returned to normality with industries restoring work and people resuming daily life activities. However, the question still is there: how to avoid such incidents in the future? It is no secret now that political parties have been protecting and safeguarding the terrorist elements flourishing within their ranks.
There has always been one reason or the other for these, be it ethnic or sectarian, mainly because language and colour have replaced commonality and brotherhood, the essence of Islam. Unless and until those in the government initiate indiscriminate action against those responsible for all this bloodshed, such incidents cannot be halted in the future.
