To everyone saying she didn't deserve to go to prison, read her Wikipedia page. She had a long history of attacking people, physically abused all her partners and had been previously arrested for waving a gun at and threatening to shoot a previoyus boyfriend.

Adittionally, from the angle of the shots they could tell that she had shot him when he was already on the ground.
