Neighbors had been talking of strange sightings and we found tracks behind our shed. We carefully tried to id the track by using a hand for size comparison. Then we took a picture so we could look closely without messing up the track. We finally saw the claw mark at the end of each toe pad and knew we had a canine, not a feline track. Whew, no Mountain Lion!
I think if most people would check out the evidence before drawing conclusions and overreacting, we could all rest better.
Ethics can include gathering evidence to substantiate a claim. Safety can be achieved by having knowledge and taking necessary precautions.
