Detailed Explanation: It was heart-breaking to see what happened in Mumbai. Although it is easy to blame the "system" for lack of "intelligence", it is simply not possible to believe that none of the citizens who were around the area where terrorists docked did not see them coming. Most probably someone who saw, did not think it was important enough to escalate to the police. ("Chalta Hai" attitude).
Such incidents can be reduced, if ordinary citizens keep their eyes and ears open when they are out in public places doing their regular things and escalate them when something suspicious is seen.
What I propose is a web-application to organize and schedule a vigil whereby volunteers can opt-in to keep their "eyes and ears open" at a particular public place for a particular time-slot.
Other volunteers can see what places and time-slots are already covered and opt to vigil some other area / time-slot.
BTW not sure if this post is relevant in this forum. Sincere apologies if that is the case.
What do fellow hackers think about this idea?
