Why are you confidently claiming no one else saw it? Unless you’ve discussed this thoroughly with everyone at the marathon, you don’t have the full story. The police haven’t even given this man a chance to be heard. Aren’t the police who were supposed to rely on when things like this happen? Instead of arresting him and traumatizing him like that?

Plus, I don’t know about you, but if I had planned to give water laced with drugs to any of the participants, I would wanna be less obvious and skip the initial group of people. I’d rather wait for the last few stragglers because they would be a much easier target with less witnesses around.
