Low and Slow and Brian D
In law the term is negligence full stop. You are either negligent or not.
Brian, Day's introduction to negligence is acceptable. If however, he introduced various categories of negligence as you state
Degrees of Negligence
- Minor Degree
- Gross Degree
- Recklessness
- Disobedience
then he is way out of tune with the legal approach to neligence.
