Wyoming just became the fourth state to pass Constitutional carry, removing the requirement that citizens obtain a permit to exercise their fundamental right to bear arms.
Similar bills are pending in states including Colorado, Minnesota, Montana, New Hampshire, South Carolina and Utah.
Back in the 80s, when the 20th century fad for bans on carrying guns started to lose its novelty, a lot of people (inside and outside the gun rights community) were uneasy about the trend toward shall-issue permits. Today it's completely uncontroversial outside a dwindling handful of extreme anti-gun enclaves. There's a good chance we're seeing the beginning of the same trend in permitless carry.
At the beginning of the 20th century, you could carry a handgun almost anywhere in the country, and nobody had ever heard of a carry permit. The subsequent experiments with gun control as a means of making society safer have failed utterly, and it's time to put them out to pasture.
