Unfortunately in my view, according to the previous article the staff will not actually be armed. The firearms will be "hidden", not carried on body.
“A teacher interacting with kids, or especially one on the floor with kids, that’s not really feasible to have a firearm on their body,” [Superintendent Steve] Clugston said.
What's really interesting in the first linked article is that it states there are about 300 ISDs that have armed, non-cop, staff. That's a big jump from the last time I looked, so about 25% of the 1227 (IIRC) schools (including charter school) have done this.
I also recently read, but cannot find the link at the moment, that only about 12 schools have gone with the top-down developed, statutory "Marshal" plan, and all the rest with the grass-roots developed "Guardian" plan.
