I heard that “drag him across the threshold” meme for many years, but at my farm/nursery’s range, years ago, I asked a customer (sheriff) who was shooting with me, and he got dead serious: “DON’T EVER DO THAT! We’ll know in under 60secs.”
Yeah that will work in the movies, but that’s about it :)
And if this guy was hot in the back, the “i thought he had a gun” wont fly either. He’ll get toasted.
