You haven't used logic. You are apparently unfamiliar with it. Refuting you is a simple matter of looking up the information and citing it, it's not even a challenge. You're clueless. I don't just accuse you of making personal attacks, that's practically all you've done and everyone reading this thread can see it. Your whole style of argument has been to make unfounded declarations and then attack anyone who disputes them. I believe you've been suspended before for such behavior. I guess some people need more than one lesson.
That doesn't stop me from knowing that I can do it. I found out that my son could have fired those shots when he was fifteen years old. The fun thing is standing by the "sniper's nest" and listening to the old time Texas people who look out the window [the one next to it because the nest has glass partitions around it] and realize what an easy shot it was. Oswald should have used a scoped pistol. He could have fired twice as many shots.
You really shouldn't whine so much. Its unseemly.
