It's a dimension of neglect. If I run a service advertising itself as preventing people from harming themselves or each other (e.g. a mental health institution), then it would be criminally negligent of me to not limit people's access to sharp knives.
That is an excellent point. My recent coursework at Penn State, there were guardrails around cheating using Honor Lock, I am guessing a motivated student could find ways around it, but the system was better than trusting students to do the right thing.
