LHO had to be shown to alleviate suspicions of police brutality and injustice.
Congratulations, thanks for proving my point that even though you claim that the Dallas Police setup Oswald by replacing the Mauser, forged Oswald's palmprint, planted bullets, planted shells, planted a jacket, planted a revolver and host of other nefarious nastiness and then the Dallas Police who had full control of Oswald just let him speak freely and in turn leave themselves at the mercy of Oswald's mouth?
As if!
The only reason they let Oswald speak is because nobody cared what Oswald said because Oswald had nothing to say.
