Given her version of events, it is gross abuse of power to charge her with 1st degree murder.
Her right to a speedy trial will certainly be violated, and a judge will violate the constitution by setting bail so high she couldn’t possibly pony it up.
Despite the fact that it looks like self defense, she’ll spend years in jail before she ever goes to trial.

I understand that for a person suffering a traumatic event doing normal things makes them feel more normal.
But a prosecutor reviewing the case is likely to see this as tampering with the crime scene and disturbing evidence. Most likely he will present it to a jury as altering evidence to support the self-defense plea.
