I don't know, I'm torn between sympathy, empathy and all out "serves them right".
You see I have two daughters of similar age and I look at their photos and I empathise with their parents who must be going through all kinds of hell, and I sympathise with them as young naive girls who COULD have been caught up in something that they had no clue of how to get out of.
Just as a "for example" a friend of our family has a 22 year old son who found himself unemployed after serving an apprenticeship and so took his savings of around £1000 to Ibiza for the summer, told his mother he'd be back when it ran out, would get a job in a bar etc etc etc, like thousands before him. On the third day away he rang his mother and asked her to put some money in his bank account as a lap dancing bar had just extracted £800 for one night out, fortunately she'd made him keep a couple of hundred at home for a return flight and thats how he found himself sitting at home after a very short trip to Ibiza.
Yes, its naivity and yes its stupidity, but thats 22 year olds for you and thats how easy it is to get involved with something that you had no intention of doing so, fortunately he had a good relationship with his family and was able to admit to being dumb.
On the other hand they might have planned the whole thing themselves...
