dogs are still THE best warning device for intruders...
In light of the outbreak of trigger happy caniphobic LEOs, perhaps the old G³ might prevail: Gravel, Geese and Gunnery
most criminals don’t want to take a chance with the dog.
I have long observed that LEOs don't compete with criminals, they complement criminal gangs by harassing citizen, shaking down the public through victimless "code enforcement", and in this case, disarming potential vics to help create a safer work environment for the crims.
Working in concert, it makes for a more holistic approach to pillaging and terrorizing the public.
Psychological Testing...such as the MMPI test...reveals that criminals and police have the same pattern.
