Mine too, but I don’t think firing on a uniformed officer chasing a fleeing suspect is worth the sacrifice and I dare say a jury would not either, even here in Texas. Maybe a few moments of situational awareness before pulling your trigger is prudent.
How would I or any other homeowner be expected to know any of that, or even glean it from the situation? It is not as if this policeman identified himself, contacted the property owner or anything like that. He just hopped a fence and started shooting stuff. If some black-clad ninja comes around shooting up my property I will defend it.
