The police (FBI and ICE included) are never your friends. They work to protect the rich and powerful and not us.
Cynical responses like this are meant to make the speaker sound smart, but actually what you're doing is making further tyranny more likely, because you're deliberately overlooking that-- whatever the existing problems with the FBI-- there is a significant difference between their behavior now and their behavior before.
Not even bothering to run the established investigation playbook when law enforcement kills a civilian is a major departure, and one worth noticing. But if all you do is go "same old same old", then you can safely lean back in your chair and do nothing as the problem worsens, while calling yourself so much smarter and more insightful than the people around you.

They work to protect the government. Now, for peasants there isn't much of a distinction, but the rich and powerful would do well to remember it.
