SYDNEY, April 18, 2013 /PRNewswire/ -- The horrific bombings that occurred at the Boston Marathon that claimed at least 3 lives and caused injury to more than 180 people was an extremely tragic event which has once again shown that at any event and/or location at which a large crowd of people gather at will always remain a potential target area for terrorist attacks. Ever since 9/11, the US Dept. of Homeland Security has been at the forefront in terms of focusing on prevention of such attacks and improving on public safety, critical infrastructure protection and other physical security. The one single challenge the US, along with all other countries face is how to ensure public safety 100% of the time. Unfortunately, due to the volatile and unpredictable nature of terrorism, it is near impossible to ensure public safety 24/7. The patterns of such attacks are erratic in nature and can happen at any place and at any time. According to news sources, there are plans that are being undertaken to tighten security at marathon events in London and Australia during 2013. "One of the major implications that the Boston bombings will cause globally is the tightening of security at similar sporting events," says Neil Dave, Consulting Analyst, Asia Pacific Aerospace & Defense Practice, at Frost & Sullivan. The homeland security segments of critical infrastructure protection, public safety agencies and CBRN detection will increase. Preventive measures that are undertaken at events where people are required to assemble in stadiums (indoor and outdoor) are usually quite effective as there is more scope for effective crowd control at these events. At such venues, public safety is ensured by having security checks with scanners, metal detectors and so on. Also, the main advantage faced is that these venues can be strategically sealed by controlling routes of entry and exit points. Hence, at-least weapons and explosives can be detected on any persons entering such venues on the spot. On the other hand, to ensure safety in terms of planted explosives, bomb disposal and EOD (Explosive Ordnance Disposal) teams can be deployed to such venues days before the event to ensure there are no such devices found.
