One of the main roles of police is enforcing laws. Are you proposing to eliminate the enforcement of laws? If not, what is the group chartered with enforcing laws going to be called and how will it be different from police?
The article this comment is under is about police "breaking" the law, not enforcing it, so you can see I'm already skeptical of what you posit their role in society is. For not so important people like me the "enforcement" is non-existant, they show up after a crime has been committed, write a report, and do nothing. Not very different from no police force. The only time they actually do an investigation is when a bank is robbed or someone rich and influential is hurt. I'd rather just stop paying for the non-service I don't receive.
The article is also about other law enforcement agents enforcing the laws against that.
So we can trust them to break and enforce the law. Sounds confusing and like a net zero to me. Why are we paying for that?
