In hindsight, it may not have been such a good idea. No, Constable John Burton isn't hungover. He's not thirsty, nor just in a bad mood.
In January 1998, the police use of pepper spray was a hot topic. Was it cruel and unusual punishment? No, it wasn't, said police top brass. How could they prove that? Well ... newspaper photographers capture cops in a variety of scenarios - in the heat and drama of emergencies, in buttoned-down press conferences, in the long hours beside crime scenes fenced off with bright yellow tape.
But Herald snapper Mark Mitchell says he hasn't forgotten the police pepper spray demonstration in Wellington on January 27, 1998.
"These guys at the time had to go through it themselves to understand what it did," Mitchell said. "All these guys for about half-an-hour or an hour were sticking their heads in buckets of water. It was quite amusing, to be honest."
