I always assumed it was a conspiracy until I started reading about it really.
On that note, one of the things thaat at least points to Oswald being the shooter or at the very least part of a plot was - as you say someone interested (obsessed) with politics - just leaving fore the day after the president is assassinated outside the building he worked in. Kind of shrug of the shoulders and may as well go to the cinema kind of thing.
Nah.
Exactly. As noted above, Oswald was a political person. He read radical political publications (even though he had almost no money; that CIA paycheck kept getting lost in the mail), he defected to the USSR, agitated for Castro, joined the FPCC, read biographies on political persons. The only interest he had was politics.
So the president is perhaps shot right outside the building he worked (never mind about him showing no interest - none - in seeing the president) and he just leaves?
He's told (but wasn't) he could have the rest of the day off? Because of the shooting? . A shooting he never inquires about? Is the president dead? Did they catch the shooter? Was it a Walker supporter? What happened?
The evidence is that after the shooting he showed no interest at all in what happened to the president. None.
If one doesn't find that strange - and evidence of some role - then one is either very ignorant or very disingenuous. And some Oswald apologists (see above), are both.
