This week on Dave Does History, Dave is out, but the show rolls on with Lena Marlowe and Graham Calder in the host chairs. Together, they tackle one of the thorniest questions in American public life: should the National Guard be used to police our cities? Chicago often takes center stage in this debate, with violent crime making national headlines and sparking calls for action beyond what local law enforcement can manage. But bringing in the Guard isn’t as simple as it sounds. From the Posse Comitatus Act of 1878 to the Insurrection Act and beyond, the legal and historical backdrop is a minefield. Lena and Graham weigh the potential benefits of increased manpower and order against the dangers of militarizing our neighborhoods and blurring the lines between soldier and police officer. Stay tuned, because this is one conversation that reaches far beyond Chicago.
