Question: Is the song by Bukka White about a maximum or minimum prison?
Context: A square wave is a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum.  The transition between minimum and maximum is instantaneous for an ideal square wave; this is not realizable in physical systems.  Square waves are often encountered in electronics and signal processing.  Its stochastic counterpart is a two-state trajectory.  A similar but not necessarily symmetric wave, with arbitrary durations at minimum and maximum, is called a pulse wave (of which the square wave is a special case).

Race in the United States criminal justice system refers to the unique experiences and disparities in the United States in regard to the policing and prosecuting of various races.  There have been different outcomes for different racial groups in convicting and sentencing felons in the United States criminal justice system.  Experts and analysts have debated the relative importance of different factors that have led to these disparities.  Minority defendants are charged with crimes requiring a mandatory minimum prison sentence more often, in both relative and absolute terms (depending on the classification of race, mainly in regards to Hispanics), leading to large racial disparities in correctional facilities.

United States, 577 U.S. ___ (2016) , is a United States Supreme Court decision concerning the interpretation of a federal statute.  18 USC §2252(b)(2) states that a defendant convicted of possessing child pornography is subject to a mandatory 10 year minimum prison sentence if they have "a prior conviction...under the laws of any State relating to aggravated sexual abuse, sexual abuse, or abusive sexual conduct involving a minor or ward."  Avondale Lockhart, convicted of possession of child pornography, had a prior conviction for sexual abuse of his 53-year-old girlfriend under New York State law.  He was sentenced to 10 years in prison under §2252(b)(2).  He appealed claiming that the qualifier "involving a minor or ward" applies to the whole series, making his prior conviction not trigger the sentence enhancement.  In a 6-2 decision, the Supreme Court held that the phrase only modifies the final item in the series, upholding the 10 year minimum sentence imposed on Lockhart.
