“The guy who took the cell phone video said they were rolling around on the ground when he first spotted them.”
I missed that fact.
Do you have a link to any article that quotes Mr. Santana stating that the cop and guy who ended up dead were rolling on the ground?
On Thursday, a second witness spoke to CNN about what she saw. Gwen Nichols said she was in the neighborhood when she heard police cars speeding by and, curious, she followed them. She saw Scott and Slager at the entrance to a vacant lot. "It was like a tussle type of thing, like, you know, like, 'What do you want?' or 'What did I do?' type of thing," said Nichols, who said she has not yet talked to police about what she saw.

The drive-by fails to ask him whether Slager dropped anything by the body.
