Five-month-old twins in Virginia; a one-year-old in Tennessee; a three-year-old in Indiana; a nine-month-old in Texas; a three-year-old in Ontario; a nine-month-old in Tennessee. All dead, left behind in a blistering hot car within the past few weeks. I sorely doubt any of them were left intentionally, and there might be no more hotly debated topic than intent regarding these tragedies. A six-year-old saved from a hot car in Hamilton, Ontario by passersby had been left in the car on purpose. A medal to those who meddle. Thank you. But how do you solve a problem nobody thinks they have?...
