Mr. Chair, the problem with the Internet and it being relatively new technology, coupled with the fact that children of very tender years, again, do not generally report and aren't likely to follow through on charges for a number of reasons.... The short answer is there are no specific studies that I'm aware of that can directly answer your question.
I can simply speak from my own experience in relation to why it seems like the rate of reporting is so low, and then, once reported, why it seems like most charges aren't followed through on. Again, I can only speak from my particular experience in those cases.
