If only the defense of a female cop was one that every homeowner would be able to use in their shooting defenses.
The state does its best to crucify regular peons defending themselves from criminals and invaders, they never bend over backwards to see them as innocent.
If this man shot this female cop breaking into his home and killed her, would the state be so receptive to his legal team arguing the same thing? Hell no, you know they wouldn’t.
This situation has actually happened in Texas a few times over the past several years. There is a strong trend of grand juries voting to not indict. No-knock raids are very dangerous to the lives of cops, even if they yell out "Police". How is the resident to know it's not just an armed robber yelling those words. If I was a cop tasked to go on a no-Knock raid, my response would be, "Thanks, but no thanks. We can take him down when is is out in public when we can control all the circumstances."
