Agreed 100%But I do not want the cop to be fined, just for him to pay for the damages (or the police force). He also does not have to be fired, just reprimanded and warned not to do it again.
And mostly injuries sustained by arrested individuals are totally down to their own actions but sometimes officers go way to far and go beyond the reasonable violence needed for a safe arrest, that alone should be open for lawsuits. Breaking a finger because you struggled so hard that you broke it due to your own struggling then sorry, no lawsuit allowed against the police officer.
Now if that officer broke your finger after you were in cuffs then yes, that would be a case in which a lawsuit against that officer should be filed.
It all has to do with reasonable behavior. The behavior of the officer in this video might have been understandable (based on the stress officer might go through) but what this officer did was not right IMHO and that should mean paying for the damages and a warning/suspension for a few days at most.
