As far as child or teen suicides, these are human beings still developing and growing, still learning things. A parent can hover, pry, be as involved as possible and it may not be enough. My first funeral I attended was at the age of 15, a friend committed suicide. My next brush with death was learning an older classmate who seemingly was pegged as the local "golden boy" with a promising future, high school sweetheart and a great life ahead killed himself, as well. I worked in hospice care and took care of terminally ill people of all ages who wanted to "speed" up the process and opt for death with dignity instead of wasting away. It's a deep and sticky topic,touching on moral and personal levels.
Regarding the CT shooting/mass killings, more details will unfold and people will use this incident like every other mass muder spree to sensationalize and/or politicize it. The real story and most important fact is that there are families and friends who have lost loved ones and regardless of the outcome, justice is never going to be done. Laws may be passed, people will throw their opinions around, but these people still live the rest of their lives without their children, family members, and friends. A person, a single person, took it upon himself to destroy so many lives and inflict a lot of pain, suffering and damage upon many. Whatever tools or weapons used is trivial in the grand scheme. His name will be remembered, but chances are the victims' won't. They'll be known as the CT school shooting massacre or by the number of slain, but they're actual names will probably only be remembered by their loved ones left behind. This murderer will serve to inspire or inflame some future murderer to "top" the destruction played out in CT.
