I've not posted anything on the tragedy that unfolded in America yesterday. Mainly because it was a tragedy. One mad / sick / insane whatever-label-you-want-to-use "person" took the lives of many innocent children and adults.
I don't believe that there is any easy answers here - any easy ways to stop tragedies like this happening in the future. However, I've posted the link above because I think it echos many of my thoughts much more articulate than I could have done.
My thoughts and prayers are with the families of those who were involved in this tragedy.
Be kind to those you encounter you never know the future.
