General Discussion

Once the cops got on scene and saw that the "disturbance" was a playful snowball fight, that should've been the end of it. Radio dispatch, confirm no one is in danger, close out the incident, move on with your shift. Making a big deal out of what's essentially people playing is dumb.

On the other hand, people following the police and pelting them with snowballs is kind of shitty. They're leaving. Let them leave. Harassing them for the sake of it is just childish and shitty behavior.

That said, the video linked in this thread doesn't show anything prior to the officers walking out of the park so I haven't seen an objective look at what took place before the cops decided to leave.

Not every situation has clear-cut good guys and bad guys. Sometimes everyone involved acts like a shitty human being. This might be one of those times.
