Speaking with TMZ, LL said that talk over such a film would be "disrespectful," wanting no part in the film's creation at the moment.
"That's not something to even talk about because there are families that suffered, people that died. And because of that, I think it would be disrespectful to them to ... have this conversation about a film when people's lives were on the line."
Christopher Dorner commited suicide during a recent shootout with police. He was responsible for shooting attacks on police officers and their families in early February, which left four people dead and three wounded.
