4-Year Old Shooter: Baby, Get Your Gun

An angry four-year-old shoots his babysitter.
Take me back to the good old days when gun incidents involved a naughty kid playing with a gun and firing it accidentally. Now, children--babies-- shoot with intent.
This four-year-old kid, barely out of toddlerhood, got angry because the babysitter stepped on his foot. He ran to the closet, got the gun and shot the babysitter. Premeditated. Knew where the gun was. Somehow occured to him shooting would be an appropriate response. Where would he get that idea, parents?
Just three days ago, I posted scary headlines regarding children and guns. The clustering of these incidents point to a trend rather than a tragic incident. Parents must be held responsible. If you need further proof that it is the parents, check out this story about a ten-month-old receiving a gun license.
Laws must change.
