To be sure, there are plenty of farfetched JFKA CT's out there, mostly on the backdrop to the sordid event, and the subsequent cover-up. So, CT'ers often look nutty.
Furthermore, many JFKA CTs have become a platform for people to promote their ideological agendas.
OTOH, the second official investigation into the JFKA, the HSCA-1979, concluded there was a probability of JFKAC, and that likely there had been a gunshot at the GK, as the limo passed.
There were a lot of smart and skeptical guys on the HSCA, and plenty of professional staffers.
Unfortunately, the smart guys were in the minority which is why the HSCA issued their FUBAR finding of a conspiracy.
