I don't understand what you said.
Care to suggest a solution to the problem?
My apologies. I realize now that I may not have been entirely clear. I'll break up my response into two separate concepts: the FBI (a federal law enforcement agency), and the judicial branch.
For the FBI to have jurisdiction, I think there would need to be some sort of violation of the law, or the Constitution. In this case, you couldn't really sue the state for blocking access to the classes. You suggested that you wanted to go after the people that are purportedly sabotaging the enrollment. These people that you're trying to go after don't seem to be breaking any laws, so there is probably no reason for the FBI to get involved.
If you're claiming that there is some kind of violation of your Second Amendment right under the US Constitution, and you wish to bring your claim into some kind of state or federal court, the court will most likely dismiss your case on several grounds. Among other things, the Second Amendment only applies to the Federal government, and the State and Local governments through incorporation under the Fourteenth's DPC. This means that you would need to point to some government (or semi-government) entity as being the actor which has denied you of Equal Protection, or Substantive Due Process.
Unless you can prove that there was a government actor or action, you will probably not succeed on the basis of a violation of your Second Amendment right. Your rights under the Second Amendment are not civil rights, or at least not in the way that you speak of them. Unless you allege other facts, you will not be able to bring any kind of civil rights claim for a violation of the Second Amendment. Typically civil rights claims are based off of some kind of discrimination in which an individual is denied Substantive Due Process or Equal Protection of the laws based on the individual's placement into a group or class. Of the groups or classes that the court has recognized as being suspect or semi-suspect are: race, sex, religion, physical limitation, alienation, and national origin. Recently, the court has been pushing the bounds of adding sexual orientation to that list of classes, but the court has not clearly defined the correct level of scrutiny to apply to those types of cases.
Regardless, i doubt that you'd be able to allege that you belong to one of those classes unless you were to say something to the effect of, "They're denying me the ability to attend Hunter's Education courses because I am _____ (race, sex, religion, handicapped, an alien, from X country)."
