But the grocery store doesn't do surgeries or tennis lessons. If the grocery store was responsible for surgeries and doing a bad job, i absolutely would defund them and give the money to surgeons instead. Surgeons are trained at doing surgery. See what i did there? Same applies to police dealing with mental ill people. Mental health professionals should be involved instead.

This sounds like an absurd analogy but only because America doesn't know how to operate community services in any other way than with a heavy police force. It's a failure of imagination and / or unwilling to look at the rest of the world for successful examples of alternative methods.
