Yes, qwerty7778, that's possible, but why don't they want to investigate it?  Just take WTC7, if some bad guys planted stuff in it, well, then the country would accept that.  If it was brought down by the gvt because it was unstable and there were national security docs there, then the country would accept that.  If it collapsed because of fire and bad contruction, OK.  Why such a slowness to investigate, and such a desire to crucify celebrities asking questions if it was innocent? I don't know.
