RTC meaning in Telecommunication ?

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. Almost every state in the US allows for concealed carry either permitless or with a permit, although permits may be difficult to obtain in some areas.

A comprehensive 2004 literature review by the National Academy of Sciences concluded that there was no evidence that concealed carry either increases or reduces violent crime. A 2020 review by the Rand Corporation concluded that there is evidence that concealed carry either has no impact or that it may increase violent crime, whereas there was no qualifying evidence that concealed carry decreased violent crime.
