If it was concealed, how did they know he had it?
A school employee noticed and reported it.
What is the responsibility of the permit holder to keep it concealed? I think it may vary by state.

I know that in some states, open carry is very much legal, has been for years, and is legal even if the state does not allow concealed carry.
What I don’t know is whether or not obtaining a concealed carry license suddenly requires you to conceal it...but I don’t think it does.
But, once we got concealed carry in Kansas, the ‘no guns allowed’ signs started popping up everywhere; and, it is illegal to bring a gun into a properly signed building. Also, although the law has been challenged (and may have even been recently changed), the sheeple are not allowed to bring a gun into a courthouse, gubmint office, school, etc., where I’m at.
It depends on the state. Some if the weapon flashes for a second or two it does not break the law. These dumb asses reporting law abiding citizens are the problem. If some one rolls up with an AR or a weapon already out then its time to do something.
In Massachusetts, concealed means concealed. In fact, if you carry concealed and the profile of the firearm can be seen through tight clothing, that's called 'printing' and you could very well be stopped and harrassed by LEOs.
A shoulder holster under an unbuttoned sport coat just doesn't cut it here in Lefty Loonie Land.
