I watched the video awhile back, and am a little fuzzy on some details. Best of my knowledge, the couple remained on their own property, so I'd THINK any "open carry" restrictions wouldn't apply. I mean, unless you're not allowed to have a firearm at all, you CAN hold one on your property... right?
Now, if the protesters tore down a gate on their property, that definitely is an illegal action and a potential threat, I would think. Fences are in place to keep people out, a mob tearing one down seems like a slam-dunk "I feel threatened" moment.
Now, my question is, did they point the guns at anyone? I know she seemed to sweep the crowd (and hubby too) with the pistol a few times, but did he ever with the rifle? I thought he stood there holding it. His finger appeared to stay away from the trigger, and he never raised it.
Legal question- you can stand in front of your house holding a rifle, can't you? Not sweeping the crowd, but just stand there?
