Thanks for your efforts. I did not mean to diminish them.
Do you have theory on who altered it and why?
You’re welcome. No problem.
That depends on who altered it. Assuming that it is some person or persons at CNN, which right now seems to be the most likely scenario, then the most likely reason would be to sway public opinion. They no doubt have showed that video many, many times on air as well as it being used in stories online.
