The Presidential Election year is fast approaching, and to be sure, Gun Control will be an issue. At some point next year, the GOP will likely adopt a plank in the party platform will be adopted in support of the 2nd Amendment, Protecting Heller and McDonald, SHALL issue laws- basically a plank against arbitrary gun control. The GOP took the position back in the late 1860's that the 2nd Amendment applied to ALL Americans and States could not interfere. Why then? Because the GOP wanted freed slaves to be able to protect themselves and stay free.
"A man's rights rest in three boxes: the ballot box, the jury box, and the cartridge [ammo] box." -Frederick Douglass, 1867
It was because of the "black codes" passed after the Civil War that the 14th amendment was proposed and then passed. One of the stated goals of passage was to protect the right of African-Americans to possess and carry firearms for their own defense.
'The black man has never had the right either to keep or bear arms,' and that, until he does, 'the work of the Abolitionists was not finished.'" -Frederick Douglass, May 10, 1965
Now, according to a Pew Research Study, 54% of African-Americans view gun ownership in a positive light. It is also being viewed as a matter of Civil Rights
"May Issue" laws are flawed. "May Issue" laws allow the opinion of the issuer to enter into the decision of whether to issue a permit. Racism has played a factor in this decision. Dr Martin Luther King Jr. applied for a concealed carry permit in Alabama in 1956 after his home had been bombed. At the time, Alabama was a "may issue" state. Although Dr. King was otherwise qualified, his concealed carry permit application was denied. The best argument for SHALL ISSUE laws is it helps remove human factors- such as racism - from the process. If you are old enough and meet the requirements, you cannot be denied- as Dr. King was.
The bottom line is Gun Control has origins in post-Civil War racism. But, the Constitution, and our laws as American must and should be absolutely color-blind or there will never be real Freedom and Justice for all.
