However, when a civilian acts inappropriately there are legal consequences. When a police office acts inappropriately there are few legal consequences and they are very-very-rarely enforced.
I'll ask the question differently,
"Is destruction of property what you expect from rioters?" Yes, 1% or less of rioters are going to be stupid. "Should they be reprimanded?" Sadly yes, and we have specialized government entities that can utilize appropriate-force to reprimand them.
"Is destruction of property what you expect from police?" No, not even from the 1% or less that want to be stupid. That is unacceptable, their job is to protect and serve. Even from each other. "Should they be reprimanded?" Yes! but we as civilians have no legal way to do this, and even the "good cops" have no good way to do this.
