There are no Second Amendment rights being taken away here and this case has little to do with the Second Amendment except that the property owner could have exercised his Second Amendment rights by shooting the person who was defacing property.
“There are no Second Amendment rights being taken away here”
Under federal law, a felony conviction in any state makes one prohibited from possessing firearms and ammunition.
It matters not if the felony was violent in nature or not, the conviction takes away Second Amendment rights.
I agree with your defacing comment, but if a person is charged with a felony there goes their 2A rights out the window. Spray painting graffiti is not something that should cause someone’s 2A rights to be taken away. This is just government finding more and more ways to disarm people.
