It's... Literally the issue we're discussing right now though. Whether or not he should have been tased. Whether or not he was actually posing an immediate physical threat, whether or not it looked like he was actually about to start attacking people and needed to be put down.

But yes I agree the way he was pushing himself into our hero barns was illegal. But the taser isn't the 'you broke the law' gun it's the 'this man needs to be stopped immediately before he causes serious harm' gun.
