Ooh, I don't know this one.
Ok, how about this
Did the mayor die?
Was he shot with a gun?
If the answer to both of those is yes
The mayor went up to thank the priest and it was a photo opportunity. He was "shot" with a camera.
I'm only proposing that because I don't believe I'm correct. If I am correct though, I didn't mean to break the case like that... :S.
