Your self portrait is not a substitute for evidence, and although it does do you justice, you forgot to include the tin foil hat.
However, lets address your issue..
"the evidence indicates not only that it was purchased while Oswald was signed in at his job"
Here is a copy of the money order
1. Please show me where the time stamp is. It shows a date stamp, but no time stamp, so it could have been bought any time the Dallas GPO was open on that day (Tuesday, March 12, 1963) which would usually be 9am to 4pm.
2. Even if there was a time stamp, do you know when Oswald took his lunch break? If so, provide evidence of when his lunch break was.
3. Even if there was a time stamp, and even if he didn't have a lunch break at that time, what is to stop him sneaking out to buy it. Show me physical evidence that he was actually IN the TSBD at the exact time he was buying the PMO, or that he could not have made it from he TSBD to the Dallas GPO and back before being missed.
but that it was purchased at a Post Office miles away from the TSBD
Good, and that is exactly what I would do if I was buying a potential murder weapon that I did not want linked back to me..
a. Put all documentation (money orders, order forms return addresses) under a false name.
b. Purchase the money order and post the order form at a Post Office that is some distance away from where I work and where I live as is reasonably possible, and have the item send to the address for that false name in the hope that it cannot be traced back to me.
ETA: OH, and as for the GPO being "miles away" from the TSBD, that is just pure BS!
in 1963, the Dallas GPO was located in what is now the Historic Courthouse and USPO building at 400 Ervay Street. That is 1.4 km (less than a mile) from the TSBD, an easy 10 minute walk.
