I love how the greatest concern is mesirah. It’s okay to call a tow truck if we don’t involve the police. No worries that a frum yid is paying 5 tuitions and has no money to spend on towing fees.
I’m not saying you’re wrong for calling. Trust me, I would do the same, especially to repeat offenders. I’m just saying that if your only consideration is whether you’re harming a goy or fellow yidden, you’re hurting the community.
