The efforts to "defund police" would solve some of the same problems that police currently address through other means. This would weaken the influence of police unions. For example, spending more to treat drug addiction as a disease rather than paying police to address possession as a crime.
I am just curious at this choice of word that seems to be the clarion call, which means entirely different in the dictionary than what is being implied! :-/
(BTW some people actually do want to eliminate the police)
"Defund the police" in the 'mainstream' such as there is one, means to reduce funding for law enforcement and shift that funding to public health, social workers, and community programs, in a way that reduces the scope of calls police will get, and reduce the number of calls police are required to respond to.
Police Unions are not publicly funded, so defunding them doesn't make sense. Renegotiating collective bargaining agreements with unions does. "Smash Police Unions" has a nice ring to it.
I am now genuinely curious to know how this is to be achieved, and what safeguards/guarantees are to be encoded so the new org does not devolve into the existing police.
