>There's definitely a tribal aspect

I disagree, I think it's historical context. The KKK used to infiltrate the police throughout the south. The police aided and abetted domestic terrorism against black people. There are people still living who remember this. It's not tribalism to point out that you are being targeted based on your race and being sensitive to that threat. If you want to call out tribalism, call out the group that is targeting others based on race. They are the tribal ones.
