Sidestepping the "lynch mob"
If one can own a handgun in Texas, it stands to reason that there is a chance a homeowner would have a gun. If a homeowner hears noises outside the house at night, that gun is coming with them while they investigate so this shouldn't be a surprise to police or anybody who didn't announce themselves. In certain places, it's shoot first, ask questions later.
I'm certain that this method of a 'wellness check' is not standard procedure and would never have gone down this way in a white neighborhood.
