They have Ohio carry permits? (or those from states with reciprocity?)
"Open Carry. Ohio’s concealed carry laws do not regulate “open” carry of firearms. If you openly carry, use caution. The open carry of firearms is a legal activity in Ohio."
looks like there is no permit to carry openly in Ohio. I would guess that only applies when don't start pointing your firearm at people.
I watched a few minutes of the Lynch hearing, and rep Cornine saying that the killing in MN was a routine traffic stop, which has been proven not true, and that the guy had a conceal carry, which is unlikely since he has a record and no drivers license. I hope someone in the meeting disputes him.
