1) NOBODY--even MD PTCH holders or even off-duty cops can't carry on school property
So, How do you tell a plainclothes cop from an off duty cop? What about the off duty cop required to carry his handgun, and needs to pick up their kid from school?
2) you need a "Handgun Qualification License" to buy, transfer, or rent ANY handgun or "regulated firearm", which is essentially the same system IL has with it's FOID cards, except it ALSO requires you spend hundreds of dollars on a training course, and pay a fee of $20 per firearm to the State.
So, when a loved one dies and wills a handgun to someone from out of state, they can't have it?
My home state sure sucks now....
