Dozens marched from College Green Park to the Ped Mall, pushing for gun safety. This comes almost a year after the Parkland Shooting that sparked anti-gun protests across the nation.

Students Against School Shootings, SASS, said no one piece of legislation is going to do it, they're pushing for a change in American culture.

"Stop putting guns in each other's hands and work to prevent the thousands of needless deaths that result from the inaction on gun safety," said Mira Bohannan Kumar.

SASS is calling for stricter local, state and federal regulations to curtail mass shootings across the nation. One of the latest happened at a Pittsburgh synagogue in October.

"There's a lot of things that I think need to happen," said Charlotte Ramirez. "The idea that people can just purchase military-weapons is terrifying. I think the fact that if you have a domestic abuse charge you can. I think there needs to be a federal waiting period getting guns"

Until that happens, SASS is celebrating what victories it can. President Trump recently put a bump-stock ban into place. The device was used in shootings like the Las Vegas massacre. The decision has also drawn criticism from gun shop owners here in Iowa and across the nation.

"A ban of any kind is something I am not a fan of so for a gimmicky piece of plastic," said Jason Gnall of Advanced Arms, a gun shop in Pittsburg. "I think it was a little extreme."

The crowd may be smaller than last year's march but the target is still the same: change the law. The group is calling for better reporting of lost and stolen firearms, tighter gun restrictions for those with mental illness and no longer allowing domestic abusers the chance to buy a firearm.

"We're still very divided and it's going to take a lot more to get where we want to be," said SASS Outreach Director Drew Owen.

Other gun-related legislation in works, the red flag gun seizure law.

It would let courts take away firearms from a person believed to be a threat to himself or others. It was in a senate discussion this week and has gained bi-partisan support.

Students Against School Shootings first came together in the wake of the Parkland massacre. A 19-year-old opened fire at Marjory Stoneman Douglas High School, killing seventeen and injuring seventeen more.
