The problem with Ken's question is that it's not reasonable to assume the court will both incorporate the 2nd without a RKBA and acknowledge the federal RKBA in an opinion. It will deny or weaken both.
So, even though incorporating the second without a state RKBA would not change anything- as Ken argues that is what we have now without incorporation- the denial of the federal right too would allow judicial and legislative restrictions to be forced upon the states.
The examples you and I cite would still be prevented by a federal RKBA- but there won't be one.
Wait a minute. Where did I assume a favorable ruling on the Federal RKBA?
OK. I understand the "how". What about the "why"? Power grab?
