I’m a grade four teacher in a major metropolitan city. I have a male in my class who draws pictures in which he is killing other students and teachers.

A girl in my son’s fifth grade class brought a knife to school because someone had been making fun of her.

My son is on a sports team and one child seems to have it out for him even though my son doesn’t even know the child.

Are there any signs to look for if a student is going to kill someone or act out in violence?

Is there any information available about the do’s and don’ts of placing information on a website such as pictures, hobby info, personal info, and more?

My 13-year-old son bought the PC game Call of Duty.

The camp I chose for my four-year-old son had a great reputation. However, last summer a counselor was accused of sexual misconduct with a first-grader.

Our 13-year-old son has been arrested for attempted assault on his father, and suspended from school for telling a student he was going to bring a gun to school and blow everyone away (he has no access to a gun).

My daughter is eight.

I am currently doing a paper about this issue and would appreciate your input.

I am the mother of a three-and-a-half-year-old boy. Many of his playmates have toy guns and other ‘‘violent’’ toys.
