Okay... CNN is a bit ambiguous in this first part:
Two boys were arrested for making pencil-and-crayon stick figure drawings depicting a 10-year-old classmate being stabbed and hung, police said.But we'll proceed on the assumption that they meant "hanged".
While certainly a child's artwork may be indicative of psychological issues (apologies for the pop culture reference), sometimes it just means that the kids were drawing pictures. The report indicates, "The children, charged with a felony, were taken from school in handcuffs." Um... excessive?
As I look back on some of the pictures my classmates were drawing at similar ages... well, let's say that little Colin's daily drawings of military hardware in action probably would have inspired Florida to classify him as a habitual felon.
