Hmmm,...probable cause. Well,...I recall my son coming home from school one day telling me he got asked to try some drugs from no less than 22 kids during the school day (heroin, ectasy, cocaine and some I never heard of).
He was the new kid on the block, so he guessed they were trying to make him welcome.
I would call that probable cause. Maybe other schools are different. For instance, we know the heroin drop is located at a Texaco gas station about 2 blocks from the school. Nothing is done about it though. Dealers hang around there looking for kids to peddle thier drugs or to sell to.
We also know the coaches push this "drug free" steroid on the atheletes at school. They tell them, it is perfectly legal as it is not recognized by the FDA as a drug.
I don't really have a problem with it. I wish the government had not done it and it was just done voluntarily by the schools. But they prefer to hide the problem than to bring it out in public....at least in this school district.
