Pluto, can you advise me on the most effective way of screaming when you're in danger of being attacked?. For instance, what word do you use? I was thinking a very loud "Aaaaargh!" might be appropriate or maybe I should go for the classic "Helppppp!" And, what kind of voice should I adopt, should it be high pitched so as to elicit help from passersby or should it be low and confident in order to scare the potential assailants and make them think you're pretty hard...
What word did you use or was it just some kind of unintelligible squeal?
In the Leeds incident, I started screaming "help police assault!" and then yes, a general "aaargh" as loud as I could. The men said "just shut up and give us your money". However I continued to scream; and they ran off.
So to my mind screaming has three functions.
(1) It raises the general adrenaline, preparing you for a fight, a bit like the New Zealand "Haka".
(2) It helps to alert people that there is a problem and they may call the police or come to your aid.
(3) It may frighten the attackers into running off, as happened here.
