It's like if you were selling a product and promising people that it will make them look younger, but after the product makes you look younger for about an hour, it makes you look way older, but you have them review the product within the hour that it makes them look younger.

They want to know whats going through their mind when they strip naked and try to fuck a child. When is a better time to ask? Why is it bad to ask them just because they are trying to do it right now?
Why does a television show host need to know this information so badly?
For public awareness
That's what newspapers are for.
The tv show is more effective because you see it as it happens ---
