Tuff Luck for sure.
I can read between the lines:
1. You get the Citation from PD whether or not your at fault because you were in the rear.
2. You have damage to your vehicle that you must go thru the steps with your insurance company for repairs including payment of a deductable. Then they will drop you or raise your rates in the future.
3. The other driver has No Damage
4. The other driver claims injury for whiplash with workmans comp
5. The other driver gets off work at the expense of the taxpayer
6. The other driver sues for personnal injury
7. The other driver gets a few grand

8. YOU GET SHIT!!!
