Even though this is a right wing news source with which we are all fond, it may be that there are additional parts to this story that we haven’t been told.
Perhaps there is more to this story. It seemed to be a stretch that a judge would extend the use of a statute intended to ban a certain class of firearm to one not covered by the statute, owning to its unintentional and faulty behavior. On the other hand, I don’t think any guns should be banned for any reason, but that’s just me.
