as I`m a bit older (I had turned 20 at that time) ....I have no idea...I was in the military in Sweden at the time...And when this happened that year , for me it was obvious as it was the Russians being involved , as they didn’t like the outcome of Kennedy/Cuba problems.....and as everything we did in the Swedish military was train to defend the EAST of the country, my mind was ‘trained’ on Russia....and of course Oswald had some Russian ties...
