I would say that seeing bomb-making ingredients laying around the place and reporting it is a sign of common sense. Perhaps you might look at your own reasoning and evaluate your own levels of it. Sometimes emotion overrides intellect.
I once knew a girl
who designed and made jewelry
with materials
like titanium
and other such space age stuff.
Half her apartment
was mad-scientist
lab time. And I have known two
women who airbrushed
images onto
metal that they recovered
from demolotion
sites. Their garages
and homes also looked like labs
for mad scientists.
Guys layings carpets
wouldn't have known what the hell
they were looking at.
People in real life
have hobbies very different
from the kind of crap
you see on TV
and in the movies. Maybe
you would be surprised
at what "carpet guys"
would see (and be afraid of!)
in normal folks's homes.
