Quoted from fosaisu:
The facts seem to be pretty well established now and not disputed by the perpetrator. The perpetrator's actions will be just as disgusting tomorrow whether or not a police report has been filled out. If you want to discuss what the proper community response to an incident of this kind is fair enough, but what do the police have to do with that?
If it is an assault, particularly sexual assault then it should be followed through appropriately, which includes the police and a report.
Generally how it works in the real world.
I work in a nursing facility, police are called all the time for altercations between residents and or staff no matter how minor.
Nothing unusable about that.
