Not OP, but yes, "defund" meaning to reverse the excessive budgetary increases of the past 5-10 years, which increased militarization of police, alongside increasing qualified immunity precedent. Some people took "Defund The Police" to mean "No Police" (there will always be extremists, sincere or planted), and it turned out to be a terrible slogan for this reason. There's a healthy middle ground in which the police force is reduced to a reasonable level, and other services are funded, so the police with their guns and military training aren't the first responders when e.g. someone is suicidal or spraypainting graffiti.

And even if the suicidal person is holding a knife, or it's my house being spraypainted, I don't want the person shot!
