There are dozens of examples over decades of social deviants who -- having no regard for the law -- entered into restaurants across the county with the sole purpose of killing as many people as they could.
Many of these occurred before CCW laws were generally available allowing law abiding citizens to carry handguns in public. Since then there have been numerous cases, including one just a few weeks ago in a hospital, where those citizens have stopped those same type of social deviants from killing innocents.
Yet no one responding here will post a story about a legally carrying CCW who has shot up a restaurant and murdered dozens of people.
Having fear of people with no basis, no reason, and no rational is called paranoia. Let's take a look at just how many answers here begin to fit that category.
