Shoot a baby? That calls for an immediate application of the Eddie Gallagher Protocol. As in, telling the bystanders to hold the shooter's arms behind their back while a Kabar or similar blade is rammed into their chest and stomach 4-6 times in each place and then they are left to bleed out right there till the coroner's van arrives.
As for the shithead parents who abandoned their child out of selfishness: They don't deserve to be parents. Prayers that the baby recovers quickly and do not have to deal with shitty surroundings again.
