[Magdalen] School district threat shutdown.

[M J _Mike_ Logsdon]

>>>It was a threat sent to a school board member.<<<

And mentioned "two or possibly three schools", so they say.  Still, credible enough for the second largest school district in the nation to unilaterally shut down 1,000+ schools (my ~2,000 earlier was way off) and inconvenience (at a minimum of 1 for each of the 640,000 students) somewhere like 1,000,000 parents, guardians, and caretakers.  Mayor has cleared students for free public transit for the day in an effort to get those already at school back home.
