Please help.. Serious question, should the cops be called? is this guy a freak? kids involved need help?

OMG! I would call the cops! Absolutely! If those were my kids I would for sure take action immediately!! What if he tries to go to the school to pick them up and kidnap them??? Pictures of the kids in the bathtub! That is child pornogoraphy... in this istance (which it sounds like).
