David Berkowitz (a.k.a. Son of Sam) has urged the mad sniper to “stop killing innocent people.” You may remember Dave from his serial killing days when he used to walk up to random people and fire his .44 Magnum pistol at them until the chamber was empty. He claims that a 3000 year-old demon dog named Harvey told him to go out and kill. Thankfully, he has seen the error of his ways and is now encouraging others not to make the same mistakes he did. On a related note, Nikki Sixx is advising teens not to use heroin and engage in promiscuous unprotected sex and Mariah Carey is lecturing young women on emotionally stability and healthy diets.
