Forcing someone to comply with a lawful order (e.g. in this case the order that the detainee must exit her vehicle) is not meting out punishment. It is enforcing a lawful order.
A pregnant woman and unborn child was shocked over a speeding ticket. She didn't try to run and gave the cops all her information. The only thing she did was refuse to sign a legal paper without consultation. I understand the signature requirement is on the books but it is completely idiotic, especially for such a minor violation.
The first time I got such a ticket, I initially refused to sign. The cop explained that I had to sign before I could go, so I spent some time reading the entire document. This really ticked him off so he leaned in real close and quietly said “if it wasn't for that camera, I'd take your smartass to jail right now”.
I used to respect cops, know several and even wanted to be one. I'm sorry, but after interacting with them and hearing of my friends’ encounters, I wouldn't trust a random cop with a dollar. I don't know a single person that was ever helped by cops but nearly every single person I know has been screwed by them. I know many crime victims and each time they tried to get help from cops, they were completely uninterested and nothing was done. One of the incidents involved my friend's mother being shot at by burglars. They didn't even question his mother or do a single hour of investigation. I've also been witness to several incidents of violent police misconduct and there's not a damn thing we could do about it - our word against theirs. Cops know they can do anything they want as long as a camera isn't present and most abuse this power.
