As a paramedic, even I can answer that question.

In our fields, our personal safety is number one priority, closely followed by our partners and other coworkers. Patient and bystander safety.is a distant third.

IN the cops case, the only way they can ensure their safety is to secure the suspect before allowing medical treatment. And to be honest, cuffing him that soon after the runover probably would damage him that much more. IN fact, If I was the paramedic on scene, I wouldn't come close to the guy if he wasn't restrained in some fashion, as I don't need him thinking I'm the only thing keeping him from freedom.

Seriously, the guy (and the cop) were just in the wrong place at the wrong time. Pure accident. No cop that wants to continue his career intentionally pulls that stunt with that much force.

Better yet, when the cops tell you to do something, it's a lot easier, and less painful, to just listen.
