Bladder Lock Down in the Hood

One of the differences between Fairgrounds Park in North St. Louis and Tower Grove Park in South St. Louis has to do with the "accomdations," or lack thereof. In Tower Grove, the Johnny-on-the-Spots are open for business. In Fairgrounds, the single portable toilet is padlocked, which begs the question:

Are those who regulate such pressing matters concerned that the predominantly poor, African-Americans who frequent Fairgrounds Park will use the pisser for its intended purpose or do they worry that someone will steal the urine?
