I agree with you morally, but constitutionally murder need not be legislated on every level. Murder is a State crime and until the people forgot that the Federal Government is one of limited jurisdiction (trade, interstate commerce, military) murder of almost any type was nit a Federal crime.
Following your logic the UN should ban murder in the US and have courts to try a used murderers when Anerican DAs decline to prosecute
*accused not “ a used”
Thanks for validating my point previously mentioned, “And when one states that fact, the posers go off on tangents of the legal definitions of murder, etc.”
