Answer:
Second amendments
Explanation:
The due process clause basically prevented the law officers from taking away the privilege citizens of United States without following the proper legal proceedings.
The second amendments granted the citizens with the privilege to own guns.
The fourteenth amendment isn't always applicable to the second amendment because there are some cases where law enforcements can take away people's right to own gun without legal proceedings. For example, if the law enforcement saw a gun owner threatening other innocent bystander with a gun, the law enforcement could take away his right to own a gun from that point onward.
