You just never know how your photos might be needed

I would definitely be willing to share my photos. I would want to find the perpetrator and bring them to justice. In my opinion you should try every way to catch the person who does something like this. People like this are not mentally stable and could cause even more death. I would gladly show my photos to the FBI, and if they wanted my help in any other way i would gladly bring that dude to justice.
