I’m not going to call anyone who has drawn a loaded weapon an “innocent”. All belligerents are a danger to me and the people I car about. If they have badges, dangerous. If they are criminals, dangerous. If they are fuck up idiot vigilantes, dangerous.
The good guy with a gun is an insidious myth from Hollywood movies. If you’re not at the range or hunting, your gun makes you a risk to public safety. And as soon as it is drawn, you are a BAD GUY.
Also consider that if the cops get called to an active shooter scenario and you're the 'good guy with a gun' that just took down the 'bad guy' .... well, now you're the active shooter.
