It's probably just a harmless meth needle. If you've ever seen a junky shoot up, then you know they're aren't going to leave anything in the syringe. The biggest threat now is just hepatitis or HIV. Maybe the school should reconsider why they are allowing students to use the restroom at a public park. I would say a little common sense could dictate the disadvantages of that. Oh, and also next time try and supervise a little better so the little girl doesn't have the opportunity to stick the needle in half the class.
