A police officer's second use of a Taser on a Christchurch man was unjustified, the Independent Police Conduct Authority (IPCA) has found.
[...]
The IPCA found the officer's first use of the Taser was justified, but that the weapon could not be used on an uncooperative, non-aggressive person to induce compliance.
Authority chairman Judge Sir David Carruthers said the second Taser use "when the man was on the ground and clearly still affected by the first use" was unjustified.
"While the man did not immediately roll over, there was no immediate threat of harm to anybody.
"The second use of the Taser was for compliance and should not have been used. It amounted to a breach of police policy, was disproportionate in the circumstances and an unjustified use of force."
There's a name for "unjustified use of force": assault (in this case, with a weapon). And I'm left asking the same question as I was last month: will this officer be prosecuted? And if not, why not?
