Who the fuck did this shit???
No seriously, destroying books through urination? The fuck hell now??
The allusions to 'alcohol likely being a factor' in the article heavily implies that the staff assumes this was the work of a homeless person. Maybe, though I wouldn't assume so. The downtown library in Lincoln, Bennet Martin, is, an urban downtown library, and as such is a common gathering place for homeless folk. (In fact, it's been an not-so-indirectly implied reason for snipping at library funds in particular whenever some spasm of budget cutting comes around) But they know the building, as well as you know your house. They know where the bathrooms are.
