Are you the actual transferee/buyer of the firearm(s) listed on this form? Warning: You are not the actual buyer if you are acquiring the firearm(s) on behalf of another person. If you are not the actual buyer, the dealer cannot transfer the firearm(s) to you.
This question is designed to see if the buyer is actually performing an illegal straw purchase.
Are you an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug, or any other controlled substance?
Because users of illegal drugs are always truthful, and will admit to being a criminal.
Are you an alien illegally in the United States?
Again, criminals always admit their crimes, because they are honest people.
Because of this, it is obvious that we can eliminate the problem of terror attacks by simply adding one question to the 4473:
Do you plan on committing an illegal act with a firearm? An illegal act would be murder, workplace violence, a hate crime, or any other crime which would involve shooting or threatening to shoot, another person or persons?
Problem solved. Unless, of course, you admit that this would do nothing, which would mean that all of the questions on those hundred million or so 4473s are a useless waste of time.
