I also agree about the minor...although you realize we are talking about a fictitious person, since Ritter was apparently communicating over the internet with a cop. What is relevant is how old Ritter thought she/he was.
And what I would like to know is if there are other instances of this.
Very relevant. Because there's a great deal of difference between a 17 yr old college student with a birthday coming up, who is coming on to you - and a 10 yr old girl.
