"can't be bothered to get physical"
Have you seen the damage done to a human body when a bunch of burly men throw it to the ground of a car park?
Presumably if they had done that, and he had lost a few teeth, or broken his nose, or broken a rib (you know, the usual), then you would be complaining about their violent bully tactics, and that they should have used the tools provided for exactly this situation... The taser.
There is no safe or harmless solution in this situation. Any action is going to have a potential harmful outcome. Thank god we have people like you to criticise any and every action taken.
"Good on the man I say..." Yeah, he attacked three innocent people in the store, and you say "Good on the man...".
