my best friend's ex-boyfriend just got out of jail.

he was supposed to do consecutive 30 year sentences for second degree murder and child abuse resulting in the death
of his new girlfriend's
3 year old daughter.
he's out on a technicality.
he used to beat my best friend on a regular basis.
he killed her dog.

he used to say sweet things like "you think i'm dumb enough to hit you where people will see bruises?"

he allegedly killed the 3 year old because she was difficult to potty train.
my friend is scared.
they say they will retry.
i'm feeling homicidal for the first time in my life.
