That is a possibility but when you live in a decent area and see it first hand it blows your mind. 2 months ago my niece decided to let her 6 year old venture to the park himself to give him some independence, after all, it was just across the street. There was a dog attack just 20 feet from him. She said just a coincidence but it sure gives a parent butterflies in their stomach knowing it could have been her son. anyway, you are right, one can not be paranoid over what might happen. Think on the negative and the negative will happen.
