Never have the thought that anything is routine. We all know — from incidents in the past few months that resulted in the LODD of a fellow officer — that there is no such thing as a routine traffic stop, routine dispute call, routine anything. Every job is unique and is should be dealt with in that manner. Make sure that when you do respond to a call that can be dangerous to ensure that you have backup with you, not on the way. Back each other up, and remember, the more cops, the merrier.
Be safe out there.
