Is it possible that an actual crime has occured here. I mean the 'threat' made by the other employee, though indirect... does that constitute a crime? If so, is the handgun evidence?
I am very curious about this case and hope to hear an update once it is resolved.
p.s. To the original poster... You may want to hold off on releasing any more information to the world until you speak with your attorney.
If the Attorney route doesn't give you any results, then I would go to the media, and you may even want to contact the NRA.
And, not that I am a vengeful person, but do you ever make notes of transgressions that nearly every company commits? That would be the time to consider whether a call to whistle blower type hotlines can come in handy. Don't make any false claims... but it can give those companies more to worry about than, infringing upon a person's constitutional rights.
