No, there was a lot more that came of this (unless you're specifically referencing the snitching part).

• It's made business execs afraid.
• It's shown the working class how to have solidarity.
• It's been a rallying cry for how much the people hare the current system.
• It's given us a martyr.
• It’s taught the would be school shooters that they’ll get lots of positive attention for redirecting their targets towards those deserving. They’ll get labeled a folk hero, they’ll have people trying to send them money for their legal defense fund, they’ll get their name in the history books. They’ll get everything they ever wanted out of their act of violence.

And I'm sure there's more.
