haha, well i think that the government hides 99% of things that happen and they are working on from us anyway so it’s not that hard to see. just like when people frame people for a crime or stage someone, they sometimes get away with it and sometimes don’t. if they are smart and hide their tracks. that’s just one or a few people. this is an entire government/governments that would have done this. not everyone would have know from that government obviously, only a select few that knew what they where doing, how to hide things and how to make things look like an accident. i suppose the most damming thing that makes me believe it was planned was how the buildings actually collapsed. idk if you’ve seen the footage but by floor to floor an explosion occurs before it even starts to fall. it’s obvious (to me) that explosive devices where put there to help the buildings go down. i think overall it’s sly and well thought out planning.
