The case went all the way up to SCOTUS,which ruled 9-0 that stun guns are covered by the 2nd Amendment.
At one point the SCOTUS ruling classified the Massachusetts court ruling as "frivolous".
A court that can issue such a ruling can also see through an equally frivolous attack on the 1st Amendment.
In case anyone's interested the case I referred to is "Caetano v Massachusetts"
The Mass supremes in the 70’s ruled that the family and doctors of an elderly severely mentally retarded male with leukemia couldn’t make medical decisions for him. They were too emotionally involved and THE STATE could do a better job.
40 years later and they are still idiots.
