As researchers, we strive to mitigate any risks, either potential or real, that might be associated with participation in this research project. Understandably, you may find some of the questions to be sensitive or to cause emotional discomfort. Some of the questions ask about your experience on the day of the shooting and may be distressing to you as you think about your experiences. You are welcome to review a copy of the full survey before deciding whether you would like to participate.
