I have a daughter who is in the 4th grade and this is something I worry about every day. I worry less about a gunman entering and shooting than I do about what psychological effect is taking place on a daily basis. I have to warn her not to say anything negative about the government or to draw pictures of weapons. What is this doing to her? She is growing up knowing that what she says may bring harm to her. Free speech is gone. All the other freedoms will follow on the same path.
