I saw the video of this last night and it was very disturbing. Even more so when I found out there was no just cause for this "raid". The parents have every right to be outraged - using a scare tactic like this in schools usually has the opposite effect. I've got money saying that these kids will now be doing massive amounts of drugs - I know I would be after something like that.
It is sad what our school system is coming to.
EDITED for bad grammar
