My brother works as a cop at Amherst College and he's always
getting wildlife complaints over there. Get the skunk out of
the dining common; a fox was seen wandering around the library;
moose in a parking lot!

However one parents weekend, with the college attempting to
look its best (this is generally a well-to-do population),
he got a report that a red tailed hawk plucked a squirrel right
off the lawn in front of students and parents, carrying it
struggling away, most likely to become baby hawk food.

The parents and students wanted the police to do something about
it!

Figures.

Since Amherst and my own fair town of Northampton are official
"No Nuke" zones, and there haven't been any nuclear events, even
with Westover RAFB not too distant, perhaps a "No Predation" zone
would be useful.

It should work just about as well.
