The characters dumbness makes me unable to feel sad for them -_-

'm sorry but first: what SWAT team is so unprofessional and doesn't check the basement control center if they're searching for a terrorist in the building who is in control of the technology in it?
And second: why do they went into a the basement where the named terrorist might be by themselfs ONE BY ONE!
Of course they went to eaother get beaten up half dead or to actually die, but if the writer gonna do this to the characters then please at least give us a realistic reason why they would abandone their reasoning and enter the tigers cave.
Why must there always be such wholes in crime plots? -_-
