Pretending that cops and politicians are important to society- or worse, that they somehow define society- is like pretending tapeworms define the person and that the person depends on them.
Parasites are parasites. Don't put them on a pedestal. Parasites are not in a symbiotic relationship with you- they harm you, but they can't exist without harming you. Letting them continue to feed off of you is the most destructive form of welfare.
Expel them and let them writhe on the ground, dry up, and die. It's more consideration than they have earned.
