Set up a gofund, and everyone who supports him should contribute. The money should go for his education, or towards something he wants to do thereafter.
End of story. Wasting time whining like five year olds about the injustice, how the state should fall, leftist schtinkers (which they absolutely are), is wasting your time, and doing absolutely nothing for Azaria.
He most likely should not have shot the filth who came to murder indiscriminately without remorse, without care, and infused with severe hatred for Jews. But he did.
Put your money where your mouth is and support Azaria.
