One that would have caught the eye of farmers would have been the Speaker authorising that water sprinklers be turned on for long periods in a bid to soak protestors and force them out. It didn't flush the protestors out but did turn the grounds into a bog, with muddy run-off.
As some farmers have pointed out, if the effluent sprinkler is turned on four long periods on a farm, it normally invites a visit from the regional council environmental officers. A breach of consent would normally invite a warning, fine or even prosecution!
