I don't understand. You mean by replacing the current police force with a vigilante force? All the image says is that regular people have come out to protect people from ICE and suggests that this type of force can replace the police.
Instead of Defund the Police or Abolish the Police, we should probably say Disarm the Police. We have the UK and several other countries that prove this is feasible. And it's more rational than just getting rid of police all together. Or if you don't believe that, it's going to sound way more rational to the general public.
