I'm referring to a petty offense in the federal code of regulations, and in this instance federal park rangers are abusing the law to overstep their bounds and make an unusually high number of arrests. Every attorney I have spoken with says something along the lines of "what they do isn't right, I don't agree with it, but it's the federal government. What can you do?"
What is the first step to challenging a federal law? Does the US Supreme Court have original jurisdiction over all federal criminal cases? Does the process begin at the local US District Court?
