Information sharing between schools and law enforcement authorities was a key point discussed at the meeting.
Downers Grove Police Chief Robert Porter, the acting president of the Illinois Association of Chiefs of Police, said attendees discussed how and when educators, mental health professional and authorities must communicate about red flags raised by community members that could end in an outburst of violence.
Quinn, a proponent of a statewide ban on assault weapons, did not mention gun control in his remarks after the meeting. When asked why members of the National Rifle Association did not attend the summit, he said the invitation to the meeting was only for people in the education and public safety fields. He added that he would be "happy to listen" to ideas from the group.
"Anybody in a democracy has a voice," Quinn said.
