no permit

Concealed carry, or carrying a concealed weapon (CCW), is the practice of carrying a weapon (such as a handgun) in public in a concealed manner, either on one's person or in close proximity. CCW is often practiced as a means of self-defense. Every state in the United States allows for concealed carry of a handgun either permitless or with a permit, although the difficulty in obtaining a permit varies per jurisdiction.
There is conflicting evidence regarding the effect that concealed carry has on crime rates. A 2020 review by the RAND Corporation concluded there is supportive evidence that shall-issue concealed carry laws, which require states to issue permits to applicants once certain requirements are met, are associated with increased firearm homicides and total homicides. Earlier studies by RAND found that shall-issue concealed carry laws may increase violent crime overall, while there was inconclusive evidence for the effect of shall-issue laws on all individual types of violent crime. A 2004 literature review by the National Academy of Sciences concluded that there is no link between the existence of laws that allow concealed carry and crime rates.
