2. People aren't dieing/being permanently injured at rates that hospitals can't keep up with because of the lack of police because the movement was so effective that it has vast swaths of the population without policing. So much so standard solvable emergencies that you could normally be treated for at the hospital end up killing you due to lack of availability of doctors.
3. Those beliefs are based on studies that have been upheld and are reproducible how ineffective current policing policies are and are underperforming by numerous metrics and especially over all in areas with poverty or mostly minority population. So not paying them more money (defund)or rewarding them for underperforming, like one would a corporation that is under performing was the original goal. It has spun a vocal minority into more extreme views of abolishing the police entirely after having emotional reactions looking deeper at those numbers.
