Can someone please tell me what is going on?

A man beheads his wife...for what?
An 11 year old boy kills a pregnant woman...for what?
An estimate of 500 kidnappings in Mexico...for what?

These are our headlines. These are what we see daily and do we flinch? Do we really understand what is going on? Where this world is headed?

Someone give me an answer...are we, as a nation, as a community, as an individual desensitized by our media?
