In recent weeks, the officers in my department have avoided very dangerous situations through sheer luck.
In one case, a relatively minor hit and run became a bit more serious when the at-fault driver fled from officers in a vehicle. Policy prohibited a pursuit in these circumstances, and officers followed up later in the shift. Only after approaching the suspect’s residence did they discover the suspect was inside and armed with at least a rifle, shotgun and pistol.
It seems the suspect, a combat veteran with no known prior criminal history, had intended on ambushing officers as they came up to his home. Without getting into the specifics, luck or the protection of divine providence prevented this from turning into a bloodbath.
