Answer:
2nd Amendment
Step-by-step explanation:
The Second Amendment details the rights to 'bear arms', in this case own weapons. The Government, however, did not know how much of a controversial issue it would be.
Since people could buy guns, they had open access to killing machines, and could easily get a weapon to rob or murder people. The assassinations, starting with Lincoln, were evidence of this.
Recently gun control has become especially controversial with the shootings of Oxford, Uvalde, Buffalo, and innocent lives are being lost. I understand that some people who own guns are law abiding citizens, but a lot aren't, and I think we should at least raise the legal age to buy firearms, ban assault weapons (you really only need a handgun to defend yourself), and ban high-capacity magazines.
