I would think kicking a 15 year old girl and slamming her against the wall and slamming her face down to the floor would be dangerous to a fetus, and should not be done unless one were in danger of bodily harm.
Deputy Paul Schene and the second deputy better pray the feds don't take an interest. They are in enough trouble as it is. They could be looking at years in Federal prison. See link to post outlining penalties for violating § 242. Deprivation of rights under color of law; and § 4. Misprision of felony.
Then you charge the out of control animal with the same penalties you’d see in her jurisdiction for a death in the commission of a crime.
She chose to take the car, she chose to sling her shoe, SHE is responsible for what comes of it same as someone who strolls into a bank with a mask and weapon. Would you go feelin’ all sorry for a bank robber who got beaten down too? Since we’re now delving into hypotheticals.
Actions have consequences.
