Remind the students that these are just proposals and they have not been approved by the school board as of yet. State that, from what you understand, a parent group which is concerned with stopping drug use in schools authored the proposals. State that you heard that the group in favor of these proposals feels that there are students who do not want to get an education and are causing trouble in school. The parents involved in supporting these proposals see these proposals as an effective way to remove these students. This parent group feels that these trouble makers are taking time away from other students who are in school to learn.
Schools are where most of the drug problems exist.
With all the talk about AIDS and checking blood for the disease, this is just the next logical step. Just the people who have something to hide. If you haven't done anything wrong, you have nothing to fear from the proposals. Students are minors and don't have the same rights as adults. Express the idea that only the people who deserve trouble are going to be affected by these proposals.
