According to Thompson - WHO IS NO FRIEND OF ANY 'ALTERATION' - the original of the film left Dallas on the MORNING of the 23rd.

So Patrick is quite convinced that no alteration could have been performed during the 19 hours and 30 minutes that Zapruder had the film.

Tell you what, Patrick - I'LL CONCEDE THAT NO ALTERATION HAPPENED IN THE FIRST 24 HOURS.

Now, lets see if you can concede that it was possible after 8am on Saturday, the 23rd.

Unless, of course - you're too busy to defend your position...
