Dallas cop mistakenly thinks she is home and kills a man

Interesting to consider whether a plea bargain is likely.

If facing a murder charge & the judge denies the officer the defense of acting in the role of a police officer, then a plea down to the lesser included offense of manslaughter with the right to appeal not only the officer’s sentence, but also the right to appeal disallowance by the trial court judge of the defense of acting in the role of a police officer would be interesting & legally significant.

Such a defense denial by the trial judge could impact all police officers if upheld on appeal. I wonder if there is any case law on this point in Texas.
