Is it dangerous or need an education

In a month I heard, read a lot of story that kids used gun or children below 12 shooted someone.  Like the story of a boy sho took gun in his school and harmed his classmate.  It takes a year for a little girl to total recover and start a new life again.  It was a truma between the one who fired the gun also for the victim.

Three weeks ago, my co-worker told me a story of her son's classmate who committed suicide at their own house.  He got his parents gun from the secure place and shot himself inside their bathroom. The boy was only 10 years old.  His poor sister found him blooded and they took him to the hospital but pronounced dead.  Also, I read this story on the news today.  So when you know the details here's the link.  http://www.azcentral.com/community/gilbert/articles/2012/04/30/20120430police-shooting-girl-accident.html#ixzz1uCiDXqcx.  But remember when you have guns at home secure them and let your kids know the value and the effect of it.
