School shootings suddenly plummet to zero?

Schools around the country were ordered or recommended closed in mid-March to attempt to stem the spread of the disease, which (as of April 13 had) already infected a reported 576,695 Americans so far and killed 23,068.

"All it took was a pandemic and closing all the schools," tweeted Bloomberg editor Mark Gongloff. - Common Dreams
