You can spin this any direction you want, but without more eyewitness reports or video footage, it's difficult to dissect. Do I believe police can overreact (sometimes grossly)? Absolutely. On the other hand, if I ignored a police officer's instructions, and in doing so I put that officer in the hospital, I'm going to jail. And I'd still be there.
A couple weekends ago a block away from where I live a woman was hit by a driver who was speeding and disobeying traffic laws, the driver fled after critically injuring the pedestrian. It was a Saturday night and it happened directly in front of two bars that stand right across the street from each other...
The woman was in the middle of the street dying in front of all of us and people were making it about themselves, interfering with paramedics and cops, some even badmouthing the cops. Traffic was coming from all four directions, a woman was dying, and it was a crime scene so it was incredibly chaotic. Some motorists seemed aggravated it was taking a few minutes away from where they were going and I was worried a horrific scene was going to become even worse.
In any chaotic scene it's always best to approach as slowly as humanly possible, be respectful, and listen to instructions. Maybe the cop didn't provide any instructions and just decided to latch himself onto Scheffler's car or jump on the hood of his car. Maybe Scheffler didn't think he was a cop and thought he was event security so couldn't be bothered with listening to instructions. Who knows? There's a lot of scenarios and conclusions people jump to because they weren't there and people always seem to pick sides these days. I've found that if I try and be helpful and treat cops and or security with respect/simply listen to them things go really smoothly and there's mutual respect.
