The Spur Question

[JMadonna]

With all due respect to Uncle Sam Ream, I don't see how Booth could have had this spur pulled from his boot by the bunting and still be able to be trailing part of the flag across the stage.

It is possible that he could have changed spurs and/or the boots after his fleeing Ford’s Theater (most probably at Surratt's boarding house) but he certainly didn't do it in mid air.
