The United States has a flag code. This group of rules is not legally enforceable; however, it's rare that governments break with the code. Unfortunately, irate or just plain ignorant citizens often do so. Again, this is not illegal, and private individuals are overlooked for their behavior.
Today is Patriots Day. Not only President Biden, but Governor Ivey also, ordered all flags on public property to be flown at half-staff. Apparently the City of Sheffield missed that literal memo, or merely didn't care enough to follow it.
This is Sheffield, home to Inspiration Landing, a development with more boards than a dance hall floor. Can't it be troubled to perform this simple task? Pardon the cliche', but this omission speaks volumes about the city.
