The summer riots of 1967 and assassinations of Martin Luther King Jr. and Robert F. Kennedy in 1968 prompted Congress to reenact a version of the FDR-era gun control laws as the Gun Control Act of 1968. The act updated the law to include minimum age and serial number requirements, and extended the gun ban to include the mentally ill and drug addicts. In addition, it restricted the shipping of guns across state lines to collectors and federally licensed dealers and certain types of bullets could only be purchased with a show of ID. The NRA, however, blocked the most stringent part of the legislation, which mandated a national registry of all guns and a license for all gun carriers. In an interview in American Rifleman, Franklin Orth stated that despite portions of the law appearing “unduly restrictive, the measure as a whole appears to be one that the sportsmen of America can live with.”
