That what I am staying stop assuming they are idiots, and don't
even know how to read !!!
I bet a lot of american would joke that the terrorist will not be
able to read the signs enough to even find and board the planes.
But after 9-11, they have prove themselves capable of finance,
co-ordination, resources to hijacking of 4 planes together and by
the way they can learn to read, and even fly the planes. Till the
planes smashed into building what is impossible interm of
co-ordination, resources, knowledge now is possible.
And start assuming people have them and know how to use them then
even out soldiers. Also stop assuming that people are just going to
have a open house and let your recce team crawl into the tunnel to
do recce.
People would have been waiting for that recce team, to take them
out to demoralised and also send the message, we are professional,
don't even try.
