Hey Walt,
Perhaps "forced" wasn't quite inappropriate.
I do recall seeing articles and such stating that anywhere from 60-70% of the public believe there was some type of conspiracy - or at least a 2nd gunman. Unless figure has dramatically dropped down to below 40%, I guess I need to give our fellow Americans more than the slightest benefit of the doubt.
Remember seeing Mark Lane in 1975/76 at Purdue University. I was just a young teen but had already become immersed in the tragedy. From that point on, I really couldn't/can't understand how anyone believed otherwise.
