Teachers should be preparing to have talks with their students about the killing of three law enforcement officers in Baton Rouge, the leader of the Louisiana Association of Public Charter Schools said Wednesday.

"As you prepare to open your classrooms to teachers and students in the coming weeks, I'm sure you'll be thinking about how to have conversations about what has taken place," said Caroline Roemer, executive director of the LAPCS.

"I see it as an opportunity for educators to lead in your communities on the very difficult issue of race and conflict," Roemer said in a newsletter.

"As we at LAPCS prepare ourselves for the next school year, including planning our annual conference, we too will think about what  kinds of learning sessions would be helpful to you," she wrote.

Charter schools are public schools run by non-governmental boards.

They are supposed to offer innovative classrooms, minus much of the red tape found in traditional public schools.

About 74,000 students attend 140 charter schools statewide.

In her message, Roemer said she was "horrified and grief stricken, knowing that so many of our Louisiana charter schools are serving students from communities that  are directly impacted by violence and inequalities in our education, housing, healthcare and justice systems," she said.

Roemer also encouraged teachers to share best practices with their colleagues.

Most public schools start the 2016-17 school year in early August, just weeks after  the shootings in Baton Rouge, and violence elsewhere.

On Sunday two Baton Rouge police officers and an East Baton Rouge Parish sheriff's deputy were killed by a lone gunman.

Three other officers were wounded, one critically.

The shooter was killed by a SWAT team from the Baton Rouge Police Department.

The usually talkative Roemer conceded the shootings have left her almost speechless.

"It's rare that I don't have words, but the events that have recently taken place in my own backyard of Baton Rouge leave me at a loss for what I could possibly say that sheds any light to a very intense problem," she said.
