What aspect of Reverend Hale's character is shown when he stands by and watches Elizabeth being taken away?

To a great extent, Hale's faith in the system is shown
when he watches Elizabeth being taken away.  The scene is rife with emotional tension
all over the place.  John Proctor is screaming and protesting that he is going to get
his wife released.  Corey and Nurse stand on in mute shock.  Cheever is convinced he is
doing his part as an officer of the court and Herrick reluctantly must put her in
shackles.  Hale stands by and assures John that everything will be fine once the legal
process runs its course.  This shows Hale to be both a part of the machinery of Salem
and unaware of its motivations.  He has already spoken to both Proctors and should have
gained an understanding that the unity and symmetry that he initially was promised by
the likes of Parris is simply not present.  At the same time, Hale does not think of
objecting to Elizabeth's arrest when the evidence of the poppet is so flimsy.  It is
here where I think that Hale's character as being an apologist and part of the system is
evident.  He fails to question why a housewife is being arrested because of a small
doll.  He does not stop and ask what is being passed of as meeting an evidential
burden.  He simply accepts it as part of the legal configuration because in Hale's mind,
if the ruling bodies deem it acceptable, it must therefore be acceptable.  I think that
this aspect of Hale's character is brought out in this scene.
