Snyder v. Phelps is a case about the 1st amendment and whether it protects protestors who are speaking outrageous statements at military funerals.
It is interesting because the justices all seem to be really using their intellectual faculties without the usual partisan filter. While I am not a critic of the typical politicizing of the court, I do believe that these particular type cases cement the court's elevated status in the American public eye. There needs to be boundaries for the ideological wars so that we maintain the contours of our nation as an ideal.
This was one of those cases where America demonstrated it's greatness.
