Are Americans becoming blasé about the police killings of unarmed black men?

Nope but they sure seem to be that if a black cop kills a white person or if a black kills a black.

No, not most of us at least.

Darian Jarrott...New Mexico State Police. LODD. Killed by a known drug dealer with a criminal history during a traffic stop. Weapon used reported to be an AR-15.
Given the reaction over the recent death of Daunte Wright from Joe Biden to the man in the street and many protesters throughout the country I would say no
Americans are not becoming blasé.
But unless I missed it, given Biden’s very recent executive orders on guns, I don’t know if he commented on the NM shooting.

Look at riots in the streets. That's not blasé.
