Sure. That's obviously true. However, not very helpful to the discussion as you don't state what percent of police officers "refuse to enforce the laws"
Do 100% of police officers refuse to enforce laws? 50%? 5%. Surely that's more beneficial to talk about than simply saying "the sky isn't blue if it isn't blue".
While Daniel Pantaleo was murdering Erik Garner, 100% of the officers present did not enforce the law, and at least a significant percentage of the court system which did not convict Pantaleo did not enforce the law.
When Philip Brailsford murdered Daniel Shaver, 100% of the officers present did not enforce the law by arresting him. A significant percentage of the court system which did not convict him of any crime didn't enforce the law. The police department which reinstated him and then let him medically retire due to PTSD from the murder he committed and pays him $2,500/month pension didn't enforce the law.
Since three police officers murdered Breonna Taylor, 100% of the police in Louisville Metro Police Department has not enforced the law.
When ex-cops murdered Ahmaud Arbery, 100% of Glynn County Police Department did not enforce the law until months later after massive outcry, and more than one DA refused to enforce the law.
When a homeless man in a wheelchair was shot in the face with a rubber bullet by LAPD, 100% of the LAPD did not enforce the law. When Buffalo PD officers assaulted a 75 year old man, 100% of the officers present did not enforce the law, and 100% of the 57 SWAT members resigned from the SWAT team when other police did enforce the law. When Denver PD shot tear at a pregnant woman and her husband who were uninvolved in protests, 100% of Denver PD did not enforce the law. When a Philly PD officer knelt on a man while he said, "I can't breathe" and the officer responded, "Shut up asshole. Are you fucking stupid? That shit don't work here" 100% of Philly PD did not enforce the law.
With the exception of Breonna Taylor, these are just some of the incidents that were caught on video. There are many, many more on video, and we can only guess how many incidents weren't caught on video.
Obviously I'm not going to be able to give you an exact percentage number of how many police officers refuse to enforce laws when cops commit crimes, but how many examples do you need to see before you will admit it's too much for the current system to be salvageable?
