This being a good example of that:
Engineering firm suggested Milwaukee County Courthouse repairs in '08 An engineering firm told Milwaukee County in 2008 that the courthouse needed $350,000 in repairs to make the building safe, including fixing the upper portion of the facade from which a chunk fell off last month.
Among several suggested courthouse repairs, the firm called for spending $125,000 for "securing and sealing the entire cornice flashing."
That and other repairs were deemed "necessary to 'make safe' facade conditions that are exhibiting significant deterioration and/or distress," according to an Oct. 27, 2008, letter to the county from engineering consultant Graef, Anhalt, Schloemer and Associates.
The cornice is a decorative molding made of limestone that borders the upper perimeter of the courthouse. A volleyball-sized piece of the cornice popped out March 4 and crashed to the sidewalk. No one was hurt, but the incident prompted the county to inspect and repair the entire cornice, a job that could take up to 5 1/2 months.
http://www.jsonline.com/news/milwaukee/89885332.html To be fair, the Milwaukee County Director of Public Works does claim that the piece of stone which fell off of the Courthouse was "unrelated" to the problems outlined in the report, but either way, it does look pretty obvious that the county did not act in the best interest of public safety.
