Tasers - To be or not to be?

PC Plod yells "Stop Police!"

2x choices, with escalating options. These should be simple for the crim to consider.

Choice 1:
Stop, offer no resistance. Most law abiding citizens might hopefully follow this path.

Choice 2:
Option a. Offer resistance / flight - K9 / pepper spray / warning shot between the eyes
Option b. Offer resistance / flight - K9 / pepper spray / electric shock therapy with taser / warning shot between the eyes

What is so difficult? Who needs tasers? A waste of time, the crim might die anyway and then Mr Plod would be done for inhumanely administering torture.

A direct warning shot is the efficient way to go. Next crim please.
