The police are a bunch of wimps. If you are trained to serve and protect the public and you are afraid of a dog?
The dog is not going to kill a grown ass man, who is trained, such as that police officer. You're going to tell me a trained man is afraid of a dog bite?
What kind of trained law enforcement is he to be afraid of a dog and a dog bite to have to pull out his gun. A dog is not a life and death situation.
