Large public gatherings could be new targets for terrorists
A large group of people in a sprawled out event like the Boston Marathon bombing on April 15, which claimed three lives and injured over 180, is proof that large scale events will always be possible terrorist targets. Future precautions are already being taken for the London and Australia marathons in 2013, but their efforts may not be enough.
CBRN units will need to be deployed to any large scale events, and in one like a marathon, checking every person and place is near impossible. Explosives can be dropped off before the event and CBRN teams wouldn't be able to cover every part of the sprawling area. There are measures, however, which can be taken.
"While investigations continue to take place on this tragic event, it can be said that the overall main issue being faced here is that any such event which attracts large masses of people is a potential target for a terrorist attack and that organizations will always have to be extra-vigilant in ensuring that people are made aware of such threats," Neil Dave, Consulting Analyst at Frost & Sullivan said. "Spreading information awareness in highly crowded venues by having banners and TV screens which compel the general public to pay keen attention to any suspicious activities is a crucial step in promoting safety awareness."
Other preventives measures, like checking an arena before a crowd arrives or having security checks with metal detectors, can be used to increase security. On large scale events like the Boston Marathon, teams can be deployed the day before and entry and exit points can be watched over.
