The letter reads in part:
"On the darkest day of my 25 years at the Orlando Police Department, I wanted to take a moment to tell all of you how proud I am of the work you have done today and will do over the next days and weeks.
We have trained again and again for this type of situation. It's unfortunate that we had to put those skills to use today. But because of that training and your professionalism, we saved dozens of lives this morning."
