Are we any safer now

The best way to look at these anti-terror measures is to divide them into three parts: left of boom, on the boom, and right of boom. The ‘right of boom’ efforts focus on mitigating the effects of a bomb blast with quick police reaction, effective crowd control, proficient emergency services and better trauma care while ‘on the boom’ efforts involve using real-time physical surveillance and ground-level intelligence to physically prevent the bomb from blasting. But the most effective method to deal with a bomb is the ‘left of boom’ effort: by disrupting terrorist cells before bombs are built and planted.
