A very wise man (probably a National Rifle Association member) said the only way to stop a bad guy with a gun was a good guy with a gun. Polls indicate that the majority of people think that everyone should openly carry a gun, including teachers, nurses, crossing guards, grocery clerks, etc.
To identify the “good guys,” when someone buys, borrows, steals, or finds a gun he/she should say if he/she is a “good guy.” If he is, he should be given a “Good Guy” badge that he would wear at all times.
When people are out on the street, in a school, in a church, in a restaurant, or wherever, if someone comes with a gun and no “Good Guy” badge then the good guy with the badge would immediately shoot him because, of course, he would be a bad guy.
If a gang of kids drove down the street with no badges they would be bad guys.
