I need help with a family argument before it starts. Help please!!?

This is what happened. Monday morning I took my daughter to work( her car is in the shop). On the way home, I hit a patch of ice at a stop sign and skidded out into the middle of a state highway. Thankfully, no semi's were coming or I wouldnt be here today. My son was very upset about this, because the police never called my husband to salt( he works for the street dept.) My son e-mailed the police and asked where they were and why they wasnt out patroling and keeping an eye on the roads( they call 90% of the time to say the roads need attn.) Now my husband is really mad at my son, and when he( my son) gets home from work, I have a feeling theres going to be a big fight!! Was my son wrong to e-mail the cops?? Or is my husband being a jerk about the whole thing?? I'm to upset to think right about this, so I need people's opinions. Thanks alot!!!!
