MARIA SHRIVER 911- MY SON CAN’T MOVE

Maria Shriver  called 911 herself -- calmly -- when her son Christopher Schwarzenegger was injured in a boogie boarding accident in Malibu last weekend.

Maria told the operator, "He can't move off the beach ... maybe like a broken ribs or something like that." She explained, "It's my son ... he's awake and breathing .... he just can't move.  He's having trouble breathing."
