One of these days the fuzz will tazer some poor shmuck with a pacemaker, for yet another minor offence. See how 'non lethal' they are then.
I take the view that:
1) a tazer is a substitute for a firearm in a situation where the 'offender' is armed but not with a gun etc and the desire is not to intentionally kill the person.
2) it is used to subdue an assailant posing a physical threat to an officer or individual.
It is not used because the officers can't be bothered to get on with the job and take the short route. It is what they get paid to do after all. It is not a tool to further subdue an individual being arrested; in other words used as a cattle prod. Are people now cattle to he herded by tazer wielding faculty/state sponsored goons?
Given my experience of some who call themselves 'police officers' in the UK, I wouldn't trust them with a sharp pencil, let alone something like a tazer or firearm. In most instances the moral and intellectual integrity required to do the job is almost always a good deal short of the mark, if it's even evident at all.
Still at least getting abused at university by private security and public servants will prepare that guy for the rigours of post graduate life

Based on the article the response seems to be grossly over the top, bordering on assault. Best get your 'papers' handy in future peeps, else you'll be off to the gulag without your feet touching the ground. Or at the very least get some rubber pants to avoid potential emarrasment when your universal joint lets go under the influence of 50000 volts.

And some people wonder why ID cards are frowned upon in the UK. I take a very dim view of events like these.
Police forces are the instrument of the State to keep the monopoly of violence
So very true - do as I say, not as I do - can be found at the core of most governments. Shame really.
