parents and school officials on edge today. vague and incredibly broad warnings of violence in schools across the nation going viral on social media overnight. schools from minnesota to texas cancelling classes or ramping up security in response to the warning that originated on tiktok. the department of homeland security says there is no evidence the threats are credible. still, authorities are asking the public to remain on alert. another day of anxiety. juliette kayyem and kim druk, a mental health expert who is author of "the real rules of life." good evening to both of you. juliette, i am going to start with you. here is the thing. whether or not this threat was a hoax, the everyday threat of school violence is very, very real, and so is the fear behind all of this, is that correct?
