Yes! Gun ownership is a right protected under the Second Amendment. However, it's important to remember that not everyone has the same right to own firearms. Persons with mental illness, for instance, are forbidden from owning firearms.
It is possible to save lives by having a gun in your home. According to the CDC, there were more than 33,000 unintentional shooting deaths between 1999 and 2016.
The good thing is that concealed weapons can be carried in most states. So, even if you aren't allowed to own a gun, you still have the option of carrying one around with you.
