Gun Control & RKBA

basic civics that everyone should learn in middle school and to be a citizen. The BoR are a set of negative rights, meaning it restricts the State, not give anything to individuals since the Founders were big on Natural Law Theory. Also, group or collective rights was not a concept to them.
That means each individual has those right for simply existing. What it actually means is that the general population needs to be armed for a well-functioning militia to exist. That sentence structure was common back then.
That is also why Congress and FDR, who signed the National Firearms Act, put a tax and registration for automatic weapons instead of banning them outright. They believed a ban would be struck down. The only challenge to the NFA was about a "sawed off shotgun", which the court said had no military value.

BTW, bans on less than lethal weapons like tasers have been overturned because they are protected "arms".
