Meanwhile back to the bus.....why would someone walk 6 or 7 blocks while observing obviously stalled traffic... board this particular bus and then get off because it's not going anywhere?
Since RD Matthews' aunt, Adelaide Seuter Germany, was married and had a son with Mary Bledsoe's uncle, Jewell
R Germany, and Mary was such a dubious witness,
https://www.jfkassassinationforum.com/index.php/topic,771.msg25998.html#msg25998along with her son, Porter Bledsoe, who allegedly made $4 selling the calendar
evidence supporting an recent Oswald/Bledsoe relationship, and bus driver McWatters likely mistook his passenger,
Roy Milton Jones for an allegedly irrationally present Oswald, the only solid evidence is the bus transfer.

If it is reasonable to expect jailers to screen carefully an incoming arrestee accused of killing a cop in the recent
90 minutes, it is reasonable to expect a bus transfer, live revolver rounds, no more often than a razor blade, would have escaped the intake/booking stage search regimen of the Dallas City jailers.
