Danforth gives the premise for judging a witch in "The Crucible". Please summarize his guidelines.

When addressed  by Rev. Hale regarding the need for
lawyers to present the cases against those accused of witchcraft, rather than Danforth
and his fellow judges hearing the cases alone, the judge gives Hale his reasons for not
using lawyers.  Danforth says that in most legal cases, eye witnesses are callef forth
to give testimony against the accused.  Danforth says though, in the case of witch
accusations, the perpetrator can commit the crimes without being seen because the witch
can send her/his spirit out to commit the crime.  Danforth says that since the witches
could commit their acts without themselves moving and thus have witnesses putting them
somewhere other than where the victim was attacked, that he could then just take the
word of the victims.
