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.
They probably showed them footage of some cop getting shot by a sovereign citizen during a traffic stop to scare them into taking things seriously the same way they show you graphic images of car crashes during drivers ed
