we hear after an event like what happened in san bernardino is suspect. we heard originally, oh, he was normal guy he met the woman and wife radicalized him. that now not seems to be case. people talk about how did we miss this? more most likely we miss i had it because we can't always find it. it's, that is not saying, if there are, if there were red flags -- harris: during the time of all the metadata. >> that is exactly right. you could argue maybe the bulk data collection maybe it was hard to find the needle in the haystack. harris: maybe. >> i don't know that. if there were red flags we should have known about, maybe there were, yeah we got to ask why they weren't follow up on and why can't we do better. the simple truth we can't stop every nutjob who wants to kill people. it is ugly truth but it is the truth. sandra: the question, catherine, was there enough there, was there enough there where authorities should have caught this?
