As you watch this fight where there is no escape from what is taking place take note of the initial chaos as the first attacks happen. Then note the movement of those involved, whilst there is a lot of monkey dancing, there are also some pretty committed attacks. We do not know the cause or the consequences but the dynamics show us the unpredictability of violence and whilst training with scripts is ok it is important to off script with multiple attackers. The weapons used to stab were improvised inhalers.
