Gavin de Becker, a security / domestic violence expert who is the co-creator of a security assessment system used to protect the Supreme Court justices and other senior government officials (he is extremely accomplished and has provided expert testimony in several civil rights cases - I recommend looking up his profile on Wikipedia. He has been on several talk shows, including Oprah multiple times) is the author of the book The Gift of Fear.
In The Gift of Fear, he describes his take on police, politicians, and commentators describing an act of violence or murder as “senseless.” In short, he thinks that’s shortsighted, because if you describe it as senseless, then how do you make sense of it? Making sense of it is key to predicting and preventing violence, as the act isn’t senseless to the perpetrator.
I know folks don’t think about it from that perspective when they describe an act of violence and murder as senseless, as de Becker is specifically in the business of predicting and preventing violence, so he has a much different perspective than most. But, interesting nonetheless.
