A lot of this is the result of sensational political paranoia.
Terrorists kill a few hundred people a year worldwide. In US alone
there are about 15,000 murders per year meaning one in every 200
people dies of murder in US instead of other causes. But those stats
are not important, we are used to them. What counts is the noise of
the day. Its not the first time politicians have overreacted -
Macartyism, internment of US Japanese citizens during WWII, etc. One
day sanity may return again. In the mean time we got to live in fear
from ourselves - and maybe that's really how terrorists are winning.
