No. Defending would result in more use of force. The work would have to be done on the front end to fund the other services, and then removing funding for police once that is no longer needed.

Otherwise you get less police around, which means they feel less safe when they are in violent situations, and they move to lethal force faster.

Extreme ends of the spectrum but a 5 person pig pile is safer for the person being arrested and resisting the arrest than a 1 on 1 fight, because the 1 on 1 fight is more likely to end in the cop fearing they are going to get hurt and shooting the person.
