modality of police responses and how they change. we talk about it all the time about the clock tower incident, forward 19 years ago to columbine and we mentioned the pulse nightclub shooting. we understand law enforcement now goes to the sound of the guns. there's no more -- we don't use the modality of contain and negotiate, of let's be patient and talk to these people because in most of the instances, there's somebody looking to kill and harm as many as possible and then die by suicide by cop or taking their own life. our responses are getting better but how are we going to prevent these in the future. i can tell you that law enforcement is looking at that this morning. >> you are a resident of thousand oaks and you have been to this bar yourself before this incident?
