Don't be surprised if Area-E cops figure it out... if they've been successful laying the groundwork with community policing. Get to know the players. Get the eyewitnesses to talk. If they do ID them, then I'd be satisfied with replacement costs and spending the time to install and repair the damaged items.

...down by the Corrib Pub? They were having trouble there with the local Scumbag Jr. population long before I moved away from the area.

Boston Police have released some more info on the incident, including:

Several beer cans were recovered as well as items of clothing. A handsaw was also recovered in the woods behind the damaged park bench. Park workers recovered a small bag with various sex devices and condoms inside.

They add:

The Boston Police Department of Area 5 is outraged and sympathizes with the residents in the West Roxbury community. Hynes Filed was just recently renovated and with the addition of the sprinklers it has become a place for families to come and spend summer days with their children. It is appalling that individuals would have such lack of respect for not only the area in which they live, but also those who find joy in using Hynes Field; particularly the young children.
