Why did the SECRET SERVICE investigate columbine???

Question

u remember the columbine shooting back in 1999? well i just found out that the secret service investigated the motives behind the shooting and other stuff related to rampage shootings soon after the incident...ok, my question is, WHY would the secret service bother studying something that is not related to their job? arent secret service the guys who protect politicians...and investigate counterfeiting? whats their business with school shootings?

Answer 1

The Secret Service did not investigate the Columbine incident.  The F.B. I. was the investigative branch on that one.

Answer 2

Because when the OKC bombing happened, the FBI was responsible for investigating bombings too.
