" The legitimacy of Oswald’s alleged alias, Alex Hidell, is tainted beyond
repair by the nature of the Selective Service card supposedly found on him
after his arrest in the Texas Theater. This card bore a photograph of Lee Harvey
Oswald but the name of Alex Hidell. The problem is real Selective Service
cards never had photos on them, so the card would have been worthless as
a means of identification. It was perfect, however, for instantly associating
Oswald with the Hidell alias. Oswald apparently only used this alias twice—
once to order the unreliable rifle later dubiously tied to the assassination,
and once to order the revolver allegedly used to kill Officer Tippit. The
authorities claimed Oswald utilized a P.O. Box, under Hidell’s name, for
just this purpose. Critics quickly pointed out how senseless this would have
been, as anyone could have purchased better, cheaper weapons on virtually
every street corner in 1963 Dallas, with no convenient trail left behind. "
