TAMPA -- Disgusting and disturbing - a story out of Chicago that has you wondering what's wrong with people?

Officers say 36 people watched a Facebook Live video, of a 15-year-old girl being sexually assaulted by five men.

Not one of those dozens of people watching contacted police until her own mother came across the video.

The girl is safe with her family, and police are looking for the men in the video.

But there's still that other disturbing aspect of this story -- the people who watched and did nothing.

10News reporter Mark Rivera is asking what you would do, and what you really should do to stop violence.

RIVERA: What gets me is that there were like 40 people watching that video and they didn't do anything.

Carlos Perez, Facebook User: You know people get used to it. That's the problem here people see things happening and they get used to it.

I'll call the cops call 911 call somebody to help. You know we need help sometimes people get scared and they're afraid to call but that's really the best thing we could do.

Brittany Hill, Facebook User: I know that a lot of people feel that they don't need to necessarily intervene because they can't be seen, but there's a flip side to that. Because they should feel as though - since there is anonymity of the Internet - since they can't be seen - they should have even more of a powerful voice because they can't see you, but your voice will be heard to help somebody else.

Tom Mueller, Violence Prevention Coordinator: We're seeing all of the ills of society also being played out in digital formats these days.

That happens to desensitize people because they're so overwhelmed.

RIVERA: What tools can we bring to people who are watching right now about turning apathy into action when something negative is going on?

MUELLER: One of those is doing something direct and to be direct is to say something to someone who is making comments, who is showing inappropriate things on social media.

Say, “hey that's not appropriate that's not cool. Think of the effect that has.”

Or they could delegate. That's the second way.

They could get someone involved, they could call 911, they could call someone in authority, they could get someone in a nearby location to help, or they could try to distract.

If they see an incident on the street or among friends, or relatives, or neighbors, they might try to distract by changing the conversation – getting someone to think differently by bringing up a different topic in a conversation - instead of something about abusiveness.

RIVERA: I talk to the Hillsborough County Sheriff's Office and they told me you don't necessarily have a legal obligation to report a crime if you see it's going on. But what I think you do have and you should have is an obligation to be a decent human being. And if you see a crime going on if you see someone being hurt step up and take action step in to make it stop. Because your action is what's going to make our community a better place.
