Dem politicians are the worst. The most direct steps of causation of these events are thus:
1. Politicians and media feign outrage at the conducting of law enforcement
2. Politicians and media incite civilians to protest, agitate and impede law enforcement
3. Civilians thus motivated proceed to protest, agitate and impede law enforcement
4. Law enforcement agencies respond accordingly and civilians get arrested, injured, or killed as a result
5. Politicians and media feign more outrage at the conducting of law enforcement
6. Politicians and media incite more civilians to protest, agitate and impede law enforcement
7. Law enforcement agencies respond accordingly and civilians get arrested, injured, or killed as a result
8. Repeat steps 5-7 until inputs change, results of steps 1-7 are negative in polling, or fatigue and apathy has lost interest in the matter
The best way to keep evil men from wielding great power is to not create great power in the first place.
