Carrying a concealed weapon (prior to CCW in WI) was a misdemeanor. Now its carrying a concealed weapon without a permit and its still a misdemeanor.
That being the case its a felony because of state laws. It is possible to have a felony conviction overturned or at least changed to a conviction of a lesser crime after the fact if its at the state level. I have heard of cases where this was done after appealing to the DA and Governor. Of course this is only hearsay and can't be taken as truth but that's at least a glimmer of hope right?
As Mr. Ettin said, find yourself a lawyer who is well versed in criminal law AND firearms laws to try and fix this issue. If/once the issue has been fixed move to a more politically friendly state.
This is who we are, what we do.
