In a small studio in the bowels of the Florida Lottery headquarters building in Tallahassee, two little tornadoes of balls bounce merrily around inside two blinking bright blue machines. In an instant, some of the balls will pop up from the melee and roll down to a neat metal rack, and by the power of gravity and the even hand of chance, a new Powerball millionaire will be made.It looks simple, but every move leading up to this moment has been painstakingly, precisely planned. Every ball has been weighed with gloved hands, every machine tested and selected at random from among several identical machines stored in a coded, sealed vault. You can't take pictures during the Powerball drawings, but there are security cameras everywhere.

What some researchers say is missing is studies that say these drills help save lives.

She was lead author on a recent report that emphasized threat assessment and prevention.The report says bullying and ostracism are two of the top sources of student distress.
