Evil (islam) had been announcing its presence all over the world for many years before they actually attacked our homeland. Not enough saw it or wanted to admit it........
Even now too many try to pass the evil off on a few groups of terrorists.
The actual event could be passed off as a small terrorist group.
What opened my eyes was the rejoicing that took place around the world, even in this country.
While the number of Muslims( in this country) that would participate in terrorist activities may be small a great percentage are enablers and would likely join in if they thought they could get away with it.
BTW, something I did shortly after 9/11 was look up the phone number of the local FBI office and put it in my cell phone.
