So since registration doesn't make cars safer now it's about having a list of guns for law enforcement. What is step one in confiscation?
I think it's "make a list."
Incorrect.
Just as a citizen cannot be disallowed possession of a firearm absent due process, so too must due process be recognized when government seeks to obtain private property pursuant to the 5th Amendments Takings Clause.
Even if the state has a list of registered firearms, it must first obtain a warrant before entering and searching a private dwelling for firearms, or any other private venue where firearms might be kept.
Moreover, should a firearm be taken by the state, the property owner has the right to challenge the states taking in a court of law.
Given this considerable and appropriate burden placed on the state, the notion of gun confiscation is unwarranted demagoguery.
