2015 Charleston Church Shooting - Muslim Terrorist vs. White Terrorist

This is from the Boston marathon bombing right?

Well two importiant points:

1. The target was a BOMBER and thus can do far more potential damage
2. He attacked a large event with thousands of people, people don't know if there are any other places that might be targets.

I think the difference is "Terrorist and Lone Gunman" rather than "Muslim vs White"
