I don't believe it. you'd have more local police protecting US mosques, then protecting public schools, should anything like that happen. many NYers saw exactly that after 9-11.
best advice - keep your children home from school the latter part of the last week of October and on 11/1 & 11/2.
I omitted a line I was considering including: "and the authorities will NOT be our friends and it will take courage to do what is required."
Why is that frame significant...I just might.
