In an interview with Katie Couric Capt. Sullenberger said, "One way of looking at this might be that for 42 years, I've been making small, regular deposits in this bank of experience: education and training. And on January 15 the balance was sufficient so that I could make a very large withdrawal."
Ask Capt. Sullenberger if it can happen to you. I'm sure if you ask him what it took for him to safely ditch the plane he would say everything he had and then some.
Control the effect by anticipating and preparing for the cause. Head in the game, arms and equipment ready, anticipating resistance and ready with a trained response - ready to fly the plane when and if it becomes necessary. For the love of goodness, read Capt. Sullenberger's quote above again take it to heart and apply that mindset and preparation to your law enforcement career. That cause will result in a direct, positive and powerful effect on you.
