From Bearing Arms:

Survivors of a Colorado school shooting walked out of vigil for their slain classmate on Wednesday night in protest of politicians and other groups using it as a platform for gun control, a local report said.
The students from STEM High School, where two gunman killed a student and wounded eight others on Tuesday, began yelling from the stands that they “wanted to be heard” after two politicians and pro-gun control advocates addressed the crowd, according to the local NBC affiliate, KUSA.
