Did the tragedy at Columbine any positive effect?

So much pain was around this event and still is. Parents mourn dead children. Victims are trying to heal their wounds. Violence in schools continues. A lot of people relish the details, often interfere in the private lives of other people. It seems that evil is only multiplied.
And yet, is there anything that can be called positive effect Columbine?

Police changed protocol. This has had a positive impact in later tragedies.

People are nicer to the quiet kids

Okay, I was joking a little. Positive effect?
As [You must be registered and logged in to see this link.] said I can only think of protocol. Cause gun laws didn't change, bullying still happens, people still find ways to get guns and what about mentally disturbed kids? Are they getting the right care and treatment they need?

Oh, probably the way the media covers mass shootings now. They're a little more careful and censored with it.

At my school people would always half-jokingly say "be nice to the weird kids and the ones who look like the school shooter type"... I think we were all a bit scared, because we knew what could happen. And maybe fear isn't a good thing, but as a result bullying wasn't as big of a problem as it used to be in my school. It did still happen of course but I think it used to be worse

Yes
There is nothing that has only a positive or negative effect

I've read a massive amount of messages and blog entries written by teenagers who are literally thankful to E&D for showing them that they can do better in life than kneel down to their bullies or keep thinking about killing themselves because they feel like they are forever done with life; looks like tragedies can sometime paradoxically save some other people's lives.

Yes, it gave us something to obsess over.

You can also look at that the opposite way, what about copy cats? Not that I disagree with you, just playing devils advocate.

Kind of as [You must be registered and logged in to see this link.] said. I think Columbine as a whole is terrible, but left very subtle or often unseen and unheard positive effects. A lot of people, myself included, are thankful for what happened for changing their warped views of the world and look beyond as a nice eye-opening forewarning. Ya' know? It's a bit hard to explain, but did Columbine have any positive effects? Yes. On people.
And well, of course, police and school procedures lol
