So you need to weigh your options. On one hand you have a child whose committment to yidishkeit is shaken due to being a victim of a zealot. Who will now view every frum person as suspect. Worse yet, he will start to doubt your love for him since you didnt go after his attacker with everything you’ve got. And maybe some of his older brothers choices will start making sense.
On the other hand, you are struggling with the desire to protect the status quo because of some perceived bias against “frum yidden” by the police.
The choice is yours
