No federal court has ruled that the second amendment applies to the states --
Which other parts of the Constitution require a Federal Court to rule on them before they apply? Does a court need to rule on all new legislation passed by Congress before it applies to the States?
You jsut keep getting worse and worse over the years.
Federal law applies immediately. If that federal law is challenged, as with Emerson, then the lower federal circuit court hears the case first.
I'm saying Emerson was the only case heard at the federal circuit court level that said the second amendment protects an individual right.
Every other federal court, especially the 9th circuit, has ruled it protects a collective right in every case they heard.
