She praised the Columbine shooters as “heroes.”

It was a crude, stupid comment even if it was “sarcastic” as claimed.  But the last time I checked, saying crude and/or stupid things isn’t a crime.

Free speech means free speech.  Simply talking about school shootings in a positive way should not be a crime.  The internet is full of people saying stupid and inflammatory things.  We can’t arrest them all, nor should we even try.
