Nonsense! Actually, you threw the disparagement switch with your first response.
My first response was to post a YouTube video, with no comment, which was related to the question of your OP. You responded with 'I believe everyone has seen that video. Just wondering which protege would post it.' Wouldn't you consider that a little disparaging? I replied in #33 with no disparaging comment (unless you can indicate one). You replied in #64 including the phrase 'keep up' in response to my simple question. I responded in kind. Like I said - Sad how things go on forums like this. Lets both drop the disparaging comments shall we?
The OP asked 'How Could LHO Walk One Mile After Leaving His Room & Shoot A Cop In 13 Minutes?'. The video showed it is possible, although as you and others pointed out there are factors which were not taken into account in the test. It is also true to say we don't know whether LHO could have been moving faster than in the test or jogged at some point or how long he waited at the bus stop. So to me the conclusion has to be that it is not impossible for LHO to have got from his rooming house to be in a position to shoot Tippet in 13 minutes. Whether that is what happened is another question.
