I'll be writing a paper on these two, and I haven't been able to find much information besides they they had acquired Chinese, steel core ammunition, and the latest and last robbery was the only one with modified, fully automatic weapons. I'd like more detail on how they progressed from small time robberies to their larger, takeovers. How they seemed to think the North Hollywood Bank of America would be the same as the other banks that they successfully(?) held up. How they went about acquiring steel core ammo for their robberies, and; how the ATF described the extent of their modifications. Surely there are books and reports, but I figured I would ask you all first, because it seems like much of that information is relatively hard to find over the mass of generalized information and movie clips online. If anybody has specific sources, I'd be happy to read through them.
