SAN ANTONIO – Welcomed with a standing ovation a group of students affected by gun violence traveled to San Antonio to discuss the highly debated topic.

"I'm very happy to be here, we are very happy to be here but we are all here because of the worst possible thing that could have happened," said Cameron Kasky, a survivor of a high school shooting in Parkland, Florida. 　

Two students lost friends when a shooter opened fire and killed 17 people at Marjory Stoneman Douglas high school in Florida on Valentine's Day. Some of the survivors are now hosting Town Halls about gun control across the country as a part of the movement they launched, March For Our Lives.

"We wanted to go around and see how different communities were being affected by gun violence," said Kasky.　

Each stop on the nationwide tour draws more students who are pledging to vote and work to bring change. They all agree that there is not one simple answer.

"These are complex issues that will have complex solutions. It's our duties to stand up, speak out and find out what those solutions may be," said student Sofia Santos. 　

The students said they are determined to be the ones who turn the tide.

"Some, not all, Americans have chosen to cover their ears and close their eyes and not do anything at all," said Anthony Cruz.

"It won't work because deranged people steal guns," said Clinton Vitousek. 　

Critics say tougher gun laws won't end the violence.

"Gun laws aren't going to stop school shooting. The only ones that are going to be affected by gun laws are legal abiding citizens. And those aren't the ones shooting up schools," said Brandon Burkhart with This is Texas Freedom Force.　

Student activists said school shootings aren't the only concern. They point to rising suicide rates as another issue plaguing the country. The students, like these survivors, said some action is better than none.

"If we can't stop every single shooting that doesn't mean we shouldn't try to stop as many as possible," said Kasky.
