Unfortunately, the way your create precedents is by refusing the plea agreement and taking it to court. This didn’t happen in this case, so it’s no use to anyone.
I think we are going to see alot more cases like this one as well as more gun cases where people are asserting states rights over federal guberment rights.
Hopefully we will see more and more pro 2A decisions and courts willing to acknowledge the obvious as well as more and more RATS fearful of touching the 2A issue.
