Seven people were killed and more than 40 were injured when a gunman opened fire during Highland Park’s Independence Day parade. Since the shooting, law enforcement officials have revealed details about the gunman’s background including previous encounters with police. Despite making a threat to kill his family, the shooter legally bought a firearm owner identification and purchased multiple weapons, sparking new conversations about ways lawmakers can boost the state’s gun owner requirements.

Gun Violence Prevention PAC CEO Kathleen Sances talked with The Daily Line’s Ben Szalinski about the next frontier of gun control measures her group is pursuing at the state level, including expanding fingerprinting requirements, curtailing the sale of assault weapons and limiting magazine sizes. She said the biggest factor in the state’s rampant gun violence is that there are too many guns on the streets.
