Nobody here knows the facts and details of this case.

If she had a reasonable fear of imminent harm then the shooting was most likely justified. If not... then no.

However, in a liberal city like Houston she better have evidence or a really good story that she told only to her lawyer.

If she talked to the police other than "I feared for my life" she's probably in for a bad time.

If she doesn't have money for lawyers she's probably also going to have a bad time with this.
