DOJ!? What? If DOJ or Biden/Kamala got involved they would take the side of the killer, as they have done for two years and are still doing today.
This kind of behavior is 'exactly' what Biden has been pushing for. When Biden claimed that all Republicans and other non-Democrats are radical enemies of the State, this is the expected result of that kind of demagoguery and slander. When you tell Democrats that ANYONE who disagrees with you is an 'extremist' and a 'terrorist', then anything a Democrat does to quote, "Protect Democracy", suddenly becomes allowed.
But yes, in a very real way, Biden/Kamala/DOJ would support the killer over the victim. This is exactly what the Democrats have been promoting and were hoping would happen. They would much more likely reward the killer than to prosecute him.
