I understand what you are saying, but in the mean time how do you protect students from the random student who wants to shoot up a school? Or is that something we should not address in any form of policing way but only do so in wealthy areas that are not as used to being surrounded by gun violence? I saw on the re-play of the gathering at the White House that teachers from DC said they have entrance metal detectors and student searches at the only open entrances to the school and multiple armed officers at the school. She seemed to believe it produced a safe learning environment and the students did not mind. This was in a high-crime, high-poverty area of DC.
