Witchy woman and ideas for augmenting laws

"Michigan woman provides drugs to kids" , not shocking, "in her care", not shocking. The law stating that children under 16 in a house where prostitution took place is an interesting one. I guess it's okay if your 16 year old is around when tricks are turned and Johns come in for sex. How do you figure? While prostitution is a crime, having a 16 year old there while you do it isn't a crime? This then begs the question, is it okay for a 16 year old to become a prostitute because clearly it isn't a violation for her to be there. Although it is a crime to do it, this law seems to blur the underlying themes of the crime.

"Okay, honey! Have a good time at Trixie's house. Say hello to Bambi! Stay out of trouble."
"Okay mom!"
