Yes, he threatened McCollough by invading his home. That is a real threat. Don't expect the victim to read the invader's mind to figure out he didn't mean it. The threat is in the invasion.
Dude comes into my home unannounced, I'm gonna take him down. Even if he starts walking away, I'm taking him down because maybe he's going back to his car for a weapon, or waiting for a friend to join him. I have no idea what he's doing, only know he just invaded my home.
Now, he can absolutely outrun me and get away unscathed. I'm over 60 years old, lol. But if I catch up to him anywhere close to my home, he's going down.
