TJ Martineau Rear-Ended Massachusetts

My husband and I were rear-ended by an ambulance in stop and go traffic. There wasn't really any damage from the ambulance but when we got out to look the paramedic that got out from the driver's side was extremely confrontational with us. The other paramedic kept telling him to calm down, calling him TJ which is the only reason I actually know his name. Before we got one word out, after getting out he was already blaming us for something that was clearly his fault. Luckily my husband was able to quickly defuse the situation and since there was no damage we said we were all set with calling the police. Unfortunately the young man's attitude just really never sat right with me since then, as well as hearing him telling the other paramedic that he better take over driving now since he wasn't suppose to be driving in the first place. That statement has just really eaten at me to the point of bringing me hear. How such things are allowed to go on is beyond me.
