This looks pretty fishy to me (not just because it's on infowars either) In conjunction with NDAA which goes into effect on 03/03/12, it's ominous. There have also been numerous reports of massive amounts of military hardware building up in the L.A. area. To me these look like part tactical (flying around staples center) part evac (hovering above B of A) exercises. Kind of scary if you ask me
