You've probably seen something like the following: I'm supportive of firing everyone of them then hiring back a reduced group. Perhaps as sheriff departments, all municipal police departments are axed. I want a greater community involvement in at least who leads the law enforcement agency (which sheriff kind of do though they can easily be worse than city cops [e.g., SFPD versus SF Sheriff Dept). The reduced (defunded) police force will then have a reduced but focused purpose. Basically where deadly force can be warranted which would be few. Gone are police in traffic stops, wellness checks, domestic violence cases among other things. Those activities are taken up by newer, purposed built, unarmed (I'm thinking more mostly unarmed, no firearms) agencies, funded by the funds from the defunded police. Not saying the police cannot be there but they are for sure not the first people that comes knocking and if they do come, they are for sure not the lead agency.
In effect, it will rip out the foundations of law enforcement as we know it. In essence, they are abolished. In its place is some form of the above.
In many ways I can see why some are clamoring for a total abolition of the police. Its current form is nothing more than a militant gang. They are rarely every held accountable which is only half the problem. Their racial bias is clear. Sure not all cops and not all agencies are bad but the foundations' rotten. Time to abandon it all... then make something better in its place. It is madness to not have anything to fill the void.
Edit: Should also mention that the prison system will get nuked. Perhaps even more severely than the police. There might be a few more systems and industries too.
