I would check to see what the department use of force policy is. This officer may have very well been following his departmental procedure TO THE LETTER.
And still get sued.
Because, some police departments do not want their officers putting their hands on people. They want them tazered after verbal commands do not work.
The way things are going, police officers will not be able to use any force at all, of any kind, for fear of lawsuits.
Even in this case, if the woman is having a medical emergency, she was in the car, refusing to open the door. The window was broken and she had to be taken out of the car forcefully.
Regardless if it was a tazer or an arm bar or tickling her tootsies with a feather, she had to be taken out, either for arrest or for medical treatment.
In my opinion, this is a lawyer looking for money on something which at first glance looks heinous.
But it wasn't.
