Students of Marjory Stoneman Douglas High School in Parkland, Florida, where a guman killed 17 students and staff in February, are turning a tragedy into a movement. 

Shortly after the mass shooting students created "March for Our Lives" to end gun violence.

On June 15, "The Road to Change" tour kicked off in Chicago.

The tour is traveling to more than 20 states, including New York.

"We're fighting for gun violence prevention and to save human lives. It's not a left or right or polarizing issue. It's something we should all come together with for humanity. So it's focusing on that with every conversation we've had, we realize how much we have in common, and how many similarities we share and the differences that we let polarize us aren't as important as we let them be," said Kyrah Simon, a Parkland survivor.

The students say they do not want to take guns away, but want to prevent them from getting into the wrong hands.

The students are speaking Friday night at the New York Society for Ethical Culture on Manhattan's Upper West Side.
