Recently, a 15 year old girl killed two and herself, wounding others, at a school in the Madison, WI area. I haven't heard much lately about how she got the guns, but there was nothing at the school to stop her bringing them in- the school may have 'Gun Free Zone' signs but Wisconsin doesn't allow metal detectors in schools because it has been deemed a violation of privacy. Brilliant. If they had them, three people might be alive. I searched and the last news info I found was from late-December.
