Reminds me of th estory about the guys who recommended bear spray to be carried and little bells to be pinned on to let the bears know you were there so they wouldn't be surprised. They said the best thing about it is that the remains of the humans could be identified by the cayenne flavour of the bear stool, and the undigested bells.
The best spray is still a Remington 870 and alternating 00Buck and slugs.
