If he’s strangling her at the time she shot him I can see how that would be self-defense.
All she needed was a boyfriend to help her fake the evidence.
Did she do a lie detector? Why no previous attempts to contact police? Why not let the District Attorney’s office decide? Or a jury?
Male lives are devalued by our society at every turn. Women serve a small % of the time fo the same crime men do. Men register for the draft and die in the wars.
Women and men lived to the same age 100 years ago. Now men live 8 years less than women.
Divorce and child custody laws all favor women.
Etc. etc.
We live in a matriarchal society and this is just one example of a dead man nobody cares about.
Reverse the genders and he’d be charged that night.
