Those of us who love America and have many friends there were delighted at President Obama’s initial reaction to the Boston bombings. He said if whoever attacked the city sought to intimidate victims or shake American values, “it should be pretty clear by now that they picked the wrong city to do it.” It seemed that sanity had at last returned, after all the scaremongering of the “War on terror”, and the ghost of 9/11 was finally being laid to rest.

One day later, a million people were under virtual house arrest; the 19-year-old fugitive from justice happened to be a Muslim. Whatever happened to the doctrine that infringements of one liberty to protect another should be necessary and proportionate?

In the London bombings, four idiots killed themselves in the first incident with a few dozen bystanders, but the second four failed and ran for it when their bombs didn’t go off. It didn’t occur to anyone to lock down London. They were eventually tracked down and arrested, together with their support team. Digital forensics played a big role; the last bomber to be caught left the country and changed his SIM, but not his IMEI. It’s next to impossible for anyone to escape nowadays if the authorities try hard.
