Does television Desensitize people?

I think people are desensitized by TV, you hear of a murder on the news and all you think is . Aww that sucks, but if it happened to anyone in your family you would bawl your eyes out. Because it's on tv or in the news paper it's not being pronounced to you personaly, but any death that is deserving to be personaly felt because they deserve that kind of compassion. Despite their past life or current live, any situation involving death should be felt. Only the very worst situations , like someone who kills , rapes, or robs should be ignored.
