Actually, the SCOTUS has ruled the opposite. In the case Tinker vs. Des Moines, the court ruled that the students who were wearing arm-bands as a protest against the Vietnam War enjoyed first-amendment protection and discipline from the school was illegal. The court has been much more lenient on searches -- see New Jersey v T. L. O. However, you still need at least some reasonable ground for a search to be legal.
As for interrogations, the supreme court has yet to rule on it. There is, however, a case brewing: http://www.csmonitor.com/USA/Justice/2010/0405/Supreme-Court.... The fact that it's written in such a fashion as to be assumed that students have Fifth Amendment rights and the court cases are arguing over a technicality of pre-trial processing would seem to imply that students don't shed that right, either. Specifically: "A juvenile court judge determined that Paul did not understand that he had a right to remain silent and a right to have a lawyer and his parents present for the entire interrogation. The judge ruled that police coerced Paul’s confession."
While it's nice that fructose doesn't raise blood sugar like the other monosaccharides, you need to keep in mind that fructose gets preferential uptake treatment by the liver. If you eat too much of a food that contains fructose, you can overwhelm your liver into producing triglycerides (see http://www.ncbi.nlm.nih.gov/pmc/articles/PMC302539). While we're not entirely sure that triglycerides themselves are responsible for ill health, having elevated levels has been linked to all sorts of chronic diseases.
