Mr. President,
The solution for gun control is in controlling the bullets. We purpose you looking into a BULLET TAX. Model it like a cigarette tax since desired outcome is similar, it's a public health issue as we want people to stop shooting.
Tax it as an luxury item, as hunting or sport shooting is a luxury. This will not violate the 2nd amendment and is a good compromise on both sides. Guns are here to stay, but we can lessen the violence while adding a new source of revenue to the country.
