All over the country, in cities big and small, police departments are recruiting tiny fractions of what they used to be able to. Cleveland's graduating class from police academy this year was 9 piglets. In 2000, they had 87. Similar drops are happening all over the country. Cities may be refusing to defund, but their PDs are shrinking anyways because the vast majority of people have realized that cops are basically evil.
I think a lot of specific types of guy have been caught in their lie that they'd rush in to stop an active shooter. Now they've got plenty of potential mass shootings to stop, like 3 a day, but if they became pigs they'd have to uphold their own bullshit lies. And they're not willing, because they're cowards
