No offense and not wanting to start anything, but to get a permit to kill a raptor I believe it is a requirement to show that other means including harassment was used to ward off the offending raptor. Feeding crows would also be considered a form of harassment and is perfectly legal, even killing a endangered animal is legal without permit if personal injury is a danger. Once a predator establishes a hunting ground they usually do not leave until they are ready, and will attack a person if they feel their nest is in danger. If a raptor attacks a person that raptor is then killed by Fish and Wildlife, regardless of the migratory bird act, same as any other predator. Harassment makes much more sense than going to the extent of a permit or stitches to the scalp.
BTW a flare gun would be a fire hazard almost anywhere but the water, I was talking about a fog horn, the type sometimes used at athletic events used by spectators.
