That fucker deserved it... when young men start threatening babies it is never a good thing.
Down here last year, there was a 19 year old father who had forcefully seized his 4 month old son from it's mother... the police caught up with him and after 2 hours of negoiating with him, he suddenly flipped the baby upside down, grabbed both legs, jerked the baby over his head, jumped a few feet in the air and slammed the baby's head face first into the cement. He swung like a sledge hammer down.
Now if they treated him this way... that baby would have lived.
