My personal view is that police should maintain their qualified immunity, because unfortunately sometimes the use of force is necessary to enforce the law. However, they should also have a duty of care toward citizens that overrides that immunity in addition to mandating that they actually do protect and serve. Castle Rock v. Gonzales[1][2] really needs to be reversed or legislatively overturned.
