Analysis of To Larkin

Is it you I see go by the window, Jim Larkin—you not looking
     at me nor any one,
  And your shadow swaying from East to West?
  Strange that you should be walking free—you shut down without light,
  And your legs tied up with a knot of iron.
  One hundred million men and women go inevitably about their affairs,
  In the somnolent way
  Of men before a great drunkenness….
  They do not see you go by their windows, Jim Larkin,
  With your eyes bloody as the sunset
  And your shadow gaunt upon the sky…
  You, and the like of you, that life
  Is crushing for their frantic wines.
