Was Joe Biden the instructor?Is this the same f***ing clown that used to demonstrate "spiderman shooting the web" with a revolver? This is stupid advice about loading the first shell to be pepper spray. All that needs to happen now is for someone to switch your load and for you to deliver lead into someone who was not posing a lethal threat. I'm sure that "instructor" will be more than happy to serve your sentence in that case. If you take out the shotgun, that's because you plan to lawfully deploy deadly force, not for any other reason. Deliver the pepper spray with something more appropriate.
Also, does he expect you to manipulate the 9mm and the shotgun at the same time? And call 911 with your dick? This is all kinds of bad. I'm not even going to address the whole "I'm armed, but do not want to use any lethal force, so come take my weapon and brutalize me anyway since I'm declaring myself to be a soft target" debacle.
