Re: Aikido in a street situation
My understanding from Australian statistics involving homicide is that guns overrepresent in the deaths of self (e.g. suicide), loved ones, family and friends as compared to 'the street'. Its an approach that lead to the restriction of availability in Australia and lowering over these cases.
Thus for the lay person (rather than professional) arts like Aikido, whilst less decisive and arguably empowering, are far less likely to lead to the sad stories you read in the newspaper.
