Malcolm Wallace, since one of his fingerprints was left behind at the SE window, with 35 points matched by 30 year veteran
expert fingerprint examiner, Nathan Darby.
Malcolm was having a difficult time seeing the target, however, since he was not wearing any glasses, as per Amos Euins, so Malcom had to fire 3 shots in 4.8 seconds, as heard and described by Harold Norman on the 5th floor, right beneath the SN window.
Unfortunately, some other experts have declared 35 points match can be nullified by irregular dissimilar points between, and also, because no other shooter using MC rifle under same condition as SN boxes in window etc, has been able shoot 3 rounds in 4.8 seconds and get a head shot
there must be some OTHER shooter with some OTHER type rifle, or there were TWO shooters, one of them having a rifle that looked to Arnold Rowland to be a 30.06 hunting rifle with a large scope that Rowland could see from over 100 yds distance.
or Oswald is an incredible shooter but was suffering from and IQ of only 108 and or had some mental disorder that explains all the other idiotic choices, like not wearing gloves and having to wipe his rifle down with a rag instead, and forgetting about that palm print he left on the barrel, and forgetting to get rid that fake Alek Hidell ID card and dropping that with his wallet at the Tippet shooting scene.
