Since the 'drug using derelict' was not in the restroom, how could this be about relieving himself in the public restroom.
Because the REPORTER thought he could sell the story better if HE CLAIMED the man was only trying to use the restroom ? (yes).
The derelict was sleeping on a bench in the bus station, and this wasn't the first time. Doing so is illegal. The cop asked him to leave and he refused at first.
What would you have done in this situation ?
Not push him down and slap him.
