I can't say I consider it much of a negative at all. The first thing that came to mind, was that the unusual situation may force children to be at home, which could potentially be a Godsend IF something suddenly happens that is really really bad. Otherwise parents wouldn't be able to get their children out of locked down schools.
I don't think its possible to have the tinfoil adjusted too tight these days.
I never thought of that ... my kids are homeschooled.
