You employ a logic fallacy by suggesting that by proving activists overreacted in one incident, none of the other cases are valid.
Clearly you must understand how this does not logically follow. You cannot disprove police brutality by being able to provide examples of where police brutality didn't happen.
Police brutality is clear from both the US statistics as well as countless cases, some of which I linked to.
It is disingenious to suggest that because we argue against police shooting people dead, it means violently resisting arrest is fine. It is not okay to violently resit arrest in Norway either. That will have consequences in the courts.
Yet in Norway it does not carry an automatic death sentence where the cop gets to be the judge and the executioner all in one, as it seem to be the case in the US.
Did you not notice my example with a guy trying to attack Norwegian police with a meat cleaver? They tried pepper spraying him. They did not empty their clips in him. Only when this failed did they shoot. And they did not shoot him in the head.
It is all about having a measured response. All lives matter including that of a suspect, but the way US cops seem to operate suggests that only blue lives matter.
