One eyewitnesses testimony is pretty heavy
“He was staggering, and as he staggered towards them they opened fire with the taser and he fell to the ground like a lead balloon,” Paula Quinn, who lives opposite, told BuzzFeed News. “I could actually hear him hit the ground, and as he hit the ground the two officers just piled in on him and started kicking 10 bells out of him.
“That probably went on for a minute or two – it seemed quite long at the time, everything appeared to be happening in slow motion.”
“They reactivated the Taser about four or five times on him while he was on the ground,” she said. “I could see it very clearly – there was absolutely no threat to him whatsoever and I am absolutely shocked.”
