i did not see the beginning of this, but the report goes as follows:
motorist throws food out of window. courier, disliking littering, picks up food and throws food back in car. motorist dumps coffee on courier. courier scratches car with key. road rage ensues.

the courier is female. i 'got away' with taking pics by just doing it openly. nobody noticed me because the focus is obviously on the altercation at hand.

i followed the motorist back to his car to photograph his license plate number. he proceeded to open his trunk, take out a baseball bat, and charge me. i walked away, and was one of only two witnesses to stay at the scene and give a statement to police.
