I talked to my instructor one on one about this case. He told me that other circuits do not have to agree with the ruling, so if this were to go to court again in another circuit, the oucome could be different(for example,http://www.tennessean.com/local/archives/03/12/43494265.shtml?Element_ID=43494265) Also, in US v. Rambo in 1996 also in the 9th circuit, they ruled that there must be illegal transfer then illegal possession will follow. Well in this case there was no illegal transfer as long as he kept them. However, my law instructor explained to me that there are many gray areas in cases like these. EX: Ashcroft made all possession of weed illegal, even if you grow your own and keep it at home, it can still be taken away and then and in short, can come in conflict with the 4th Amendment. This case did not re-legalize machine guns except in the 9th circuit, as of now in the 6th circuit a man in TN is in court for virtually the same scrnario minus the convicted felon part. If ruled this case is ruled in agreement with Stewart v. US, then maybe, maybe this will be the beginning of the end of the infamous MG ban.
