Why would the NJ state constitution need to affirm R2KBA? It's in the Bill of Rights, for all Americans. While some states affirm that right in their constitutions, it is not necessary. States DO elaborate on castle doctrines(expanding those rights), more or less when you are allowed use of deadly force.
Even if it were in the NJ states constitution, it would be quickly ignored.... FFS its ignored as #2 right in the bill of rights.
States rights do not triumph individuals rights as outlined in the 10A, that is not a valid argument unless you are arguing the subject isn't a right at all.
A states rights issue on this subject is when and how you can use a firearm, not the possession or carry of it... NJ may say you need to try and retreat, while Texas and FL have stand your ground laws.. THIS IS STATES RIGHTS..
