Laudable, no doubt. But who will monitor the feeds from these cameras? Who will recognise what is dangerous, who will they communicate this to, and who will initiate preventive and remedial steps? A pretty large task, to be sure.
Security is today a tough job that requires a high-degree of training. The value of security lies in preventing attacks. It is no longer the smoking-gun that security-men look for, but they study several parameters - behaviour, posturing, patterns of conduct, clothing, body language, etc. It is a continual process, both labour- and capital intensive. Resources have to be provided over a long-term, preferably through budgetary allocations. Identifying suitable persons and training them continually is needed. Intelligence-sharing is a key component of today's security environment - the facility to know what happened elsewhere, how and why. Work should not stop at the CCTVs alone.
Finally, I am tempted to write about spectator behaviour. Like in times of war, it may be time for us to have drills for safe crowd & spectator conduct lest spectators become part of the problem. I was dismayed to see how many people stayed on to watch a bomb-disarming; what if the bomb had actually detonated?
