Course nobody should want that. That is just part of the mob hysteria created from this incident. It's sad to see the weak leaders of several cities bend over to the mob and actual plan to partially defund the police dept.
If anything, there should more investment, and that should be channeled to better training and increase salaries to start attracting better talent.
Defunding the police will not only result in more crime, but will result in being a less attractive job for the brightest and smart people in the country.
