@Anchorite, I have mixed feelings as well.
In our county, the first Monday of each month is felony plea and arraignment, where it's just a cattle call of defendants. The dockets are 20+ pages long some days.
I hope the lawyers who choose to carry do so with total concealment in mind. The opinion says nothing about conceal vs. open carry.
I don't like the idea of visible firearms in a room full of alleged criminals (some are alleged, some have substantial criminal histories already).
The defendants have to go through metal detectors before entering the courtroom. We know they don't have a gun while we're in there. So now we're going to introduce guns into the equation where they weren't before. For someone who is generally pro carry everywhere, I have misgivings.
Now this is assuming they rule that the courtroom is covered in this. The Supreme Court hasn't done so at this time. This isn't even close to being over. Justice Womack even eluded to that in the majority opinion, saying they would take up whether the courtroom was included when it came before the court. So they knew they were kicking the can down the road.
