M.J. Gohel, director of a London-based counterterrorism think tank, said the idea of home-grown British suicide bombers targeting their compatriots had elevated the threat of terrorism to an unprecedented level.
“We are now in an entirely new dimension as regard the terror threat,” said Gohel, “a new generation of terrorists, intelligent, educated individuals from solid middle-class backgrounds ... possessing all the Western social skills, no criminal record ... who fits in totally but is infected by the Al Qaeda ideology of global jihad, a hatred for the country he lives in, and the desire to destroy the democratic and secular world.”
There's a gigantic line between discontent and radicals demanding revolution and overthrow of governments. Violence throughout history has been their trademark. These people advocate assassinations and killing of "infidels" and politicians who disagree with them. To what limit do we advocate their "free speech?" Not profiling these people, or people who associate with them, is akin to giving permission to future suicide bombers IMHO.
