Reply #83: The officer was joining the pursuit of the armed felon

[Louie the XIV]

that was why he was drving so fast.

The rule is based on the principle that if you commit a felony like arson or armed robbery it is forseeable that you are creating a dangerous situation and that police and or firefighters will be called out after you. The felon here was fleeing at high speeds and endangering innocent lives it is foreseeable that this action would cause a traffic accident and death. The fact that the cop was 40 miles away at the time is irrelevant because he was driving to intercept the felon, that was the reason he was on the roads and driving at high speeds.

As a side note, in most rural areas it is not unusual at all to see law enforcement members from long distances join in felony pursuits/investigations because of the limited manpower and resources of most small town police departments.
