200 Witnesses - 85% of whom pointed to the TSBD building. The 'Grassy Knoll' story wasn't even BIG till later, AFTER the event ... as to phony SS Agents - I gotta believe with all the HOOPLA going on at the time in Texas and Dallas about the prez - that parade route had to have been CRAWLING with SS agents, in fact, ONE broadacast news report said that SS agents had been 'crawling all over Dallas for a week ' (WBAP - their "Lost Kennedy Tapes" series broadcast in rael-time, 40 years later, this last weekend) - to sum it up, this is an oft repeated old saw by the conspiracy hucksters ...

85% were closer to the Depository around Houston Street. There were just a few people near the Knoll.
