Say you’re asleep in your house. Say you’re awoken by some goon breaking into your home through a window, so you reach for your pistol to defend your home, property, and family. It is, after all, Texas; if a kid in a hoodie is threatening enough in Florida, then surely someone breaking into your house is threatening.
Gotcha! It was actually a no-knock marijuana raid (that found no drugs, and certainly found nothing to suggest the resident was a kingpin), and you just killed a cop! (A cop who has, posthumously, been awarded a Star of Texas by the governor.)
Oh, you’re also black, so it should come as no surprise that the prosecutor wants to kill you for having the unmitigated gall to defend your home against unknown intruders.
N.B. that nothing found in the raid was actionable at all. They’re trying to execute this guy for shooting at intruders. Which, of course, sounds a lot like another case I remember.
Oh, and further note that the Killeen cops were executing a no-knock, surprise warrant — basically, the most violent sort of raid — in pursuit of a drug now legal for personal use in two states. Whether or not this kind of violent, retrograde enforcement of pot prohibition is a good idea or good use of resources is left as an exercise to the reader.
