Front Air Bag Sensor Control problems of the 2000 Mercury Mystique

Rainy day, SUV vehicle in front of me completely stopped in the middle of street to make a left hand turn, he must have just stopped, because when I slowed down to brake my car slid and hit him in the rear, my whole front of car was smashed with the radiator partially up in the air, the car totalled, I would say, yet the air bags did not deploy, and it had dual air bags. I had a cut on my nose, not bad, but with bleeding inside nose, and lower back pains, my head hitting steering wheel. Also my brother has pains in his rib which we are going to the doctor forto have xrays. I believe these air bags should have deployed at time of impact, I am lucky to be alive. Please investigate this . Thank you.
