Nope.
I would let big John enjoy his day at home.
But that's just me.

And just to share something I was taught in another life...

If someone calls your buisness/home/school with threats like these, try to keep them on the phone as long as you can. (Be respectful, but keep asking questions. Yes, even see if they will give you thier name.) And even if the perp hangs up, keep your end open. They still have a chance to trace the call.
