^ Do you really think that the State of Ohio is denying her a right to a self to defend on the grounds of race and gender? Are they really criminalizing black girls and women? Would a white male of the same age have not been prosecuted for shooting his father (or mother) while they were sleeping? Would there be the same level of protest were he prosecuted? Do you actually understand the criminal justice system and the facts of this case in particular well and indisputably enough to know the proper course of justice? Bresha Meadows is much lighter skinned than her black father was. Maybe she only killed her unarmed black father because of racism and white privilege.
If the prosecutor wants to get her convicted of murder, he'll have no trouble. The State will never accept that a sleeping man was a lethal threat from which the justice system could not protect a girl. It doesn't matter if it's obviously true, the state won't acknowledge it. They certainly won't allow anyone to attempt to prove it in court. The State can't afford to undermine confidence in the justice system like that. If it goes to trial, the jury won't even be allowed to hear about the abuse. It will be suppressed as prejudicial character assassination of the victim. Also, it's Ohio - the only state where the burden of proof is still entirely on the defendant in cases arguing self-defense.
