Yes, I do. That's why I was able to figure out a long time ago that LHO killed JFK and that there is zero evidence he had even a single accomplice. I could be convinced otherwise if somebody could present actual evidence to the contrary but it's been almost 63 years since JFK was killed and the chances of that happening get more remote with each passing year.
You do understand that there is a major difference between you thinking that you know how to weigh evidence and demonstrating that you actually can weigh the evidence, right?
Some people think that whatever they believe in is always correct, when in most cases it isn't.
If you really knew how to weigh evidence, you would have been able to answer questions (which you can't and don't) and you would actually be able to present a persuasive argument instead of constantly complaining about people that don't share your opinion.
