I've had something on my mind for some time now that I would really like clarified by a lawyer or a LEO, or just someone who is familiar with the relevant law.
Every once in a while, after I get off work and make it to my humble abode, I will have a beer or two (or three

). Especially If I'm barbecuing. And shoot, sometimes I'll even have something stronger than a beer. I don't mean to make myself sound like an alcoholic, I wan't to stress that this is
occasional in nature. As the title implies, I'm very curious how the presence of alcohol in my system would affect me legally speaking should there be a need to use deadly force in self defense inside my own home. Let's say that, based on the facts, it's a perfectly good shoot under the Castle doctrine. The only other factor is that I've imbibed some that evening. I think that doing a drug/alcohol screen is routine procedure if I shoot someone, is that right? Regardless, even if the police don't test me, let's say my eyes are a little red and there are 3 empty bottles of beer over on the counter, and it's pretty obvious I've had a couple. I'm wondering if I'll still be OK under TX law. And
if I do get tested, would the BAC matter? Would there be any difference in how I get treated under the law whether my BAC is 0.02 or 0.10?
P.S. I would
never drink while carrying, but I feel like I shouldn't give up my right to consume whatever beverage I want to consume inside my own home for fear that the law will come after me should I have to defend myself in my home.
