One guy indeed has a quart of Budweiser in a paper bag. He seems neither impaired nor disorderly. The day was perfectly pleasant until these scummy pigs started yelling at these guys in the most ugly, bullying way, making everyone around them completely sick, sad, furious, disgusted. You suck at directing traffic, you never know the directions to anywhere, and the most benign thing you seem to do is remind civilians that we're never more than a hair's breadth away from a violent confrontation, because we never know when we might encounter someone who feels it's his or her legal or illegal business to force us to submit to them. Think of society as the extreme capitalists describe it.
People just do what they want.
We all have the opportunity make our own destiny. Hey, I believe that. Of course, I think our choices are products of the interaction of our own will and countless other forces. Some of those forces are social, the product of human conduct towards other humans, and therefore worthy of inspection, analysis, and critique. And some humans are armed so as to affect other humans more sweepingly or brutally than others, with economic power, legal power, or physical power.
