Here's the link Wysiwyg gives above.
It seems to raise more questions than it answers.
The witness (Ritchie) seems to have seen the video CCTV footage & tailored his testimony accordingly, and this is "wrong".
The victim's father also seems to have watched the footage, but there is no suggestion that this is "wrong".
Crawford's father and attorneys said that the footage showed the 22-year-old walking from one aisle to the next with the BB rifle at his side and in his left hand, pointed at the floor except for one notable movement. Why remove it from the original aisle? surely you can inspect it in situ and replace it on the shelf, either to leave it, or to pick one which is still boxed if you want to make a purchase.

I have to wonder what would have happened if it had been a white man who'd been in this position:
1, He wouldn't have been shot because the police are racist & don't shoot white men?
2, He would have responded to the police challenge (which they claim they made) and put the gun down?
3, He would have been shot, but there would have been no media frenzy because "White man shot by cop" is not newsworthy?
