Many times people break the golden rule of confrontation, 'engage and enrage'. The whole scenario escalates to violence, if not death. Though it is considered a felony to send your dog after someone, no jury will convict you if your antagonist is holding a knife, gun or had you in a situation where you cannot escapte and/or evade an imminent attack.
Some people are victims of violence even in traffic. Did you know that someone 'driving to intimidate' can be subject to arrest? Further, if anyone comes out of their vehicle to confront you for a traffic mistake, or road rage, once they step out of their car, they can be subject to arrest in most states.
Chances are if you had a German Sheperd Dog or a working dog in the vehicle, the situation would probably not materialize.
No question, an anti-crime or Protection Dog is expensive, however, there is no
comparison to your family and your life!
