When talking about de funding the police, it is important to ask what it means.
If you could send a social worker or professional psychologist to talk someone down from jumping off a bridge, would tha the better than sending a police officer (whose training is largely about other things)?
If de funding the police means finding other state employees who could do a better job at specific task, and transferring the current police budgets (eg drugs prevention programs run be experts to prevent the need for policing of drug use in 'at risk' communities), I suspect you would actually support it.
And it sounds like you wouldn't disagree with this.
Abolish the police is a difference (related) idea, and I suspect the major issue with it is that many armed and trained right wingers being fired from their jobs as police officers is a recipe for further far right violence and terrorism.
