No sense whatsoever

A pregnant 15 year old girl from Florida can be driven to Missouri and forced to marry the 30 year old father of her child and he can take his child bride back to Florida, and the marriage totally legal. If she leaves him before 18 because he is abusing her, she is not eligible to enter an abused woman's shelter. If he stalks her, she can't even buy a gun to defend herself for three years, because of Florida's recent gun law denying guns to adults under 21.
