I am experiencing no shock after reading this article.
I'm on the side of the police on this one, a doddery fella ambling down the street waving a white dipped stick along the ground can EASILY be mistaking for a samurai sword weilding manic by highly trained police officers.
Sarcasm?

There is no way a white stick can be confused for a Samurai sword. I normally err on the side of caution but the cops involved were idiotic in this case with no excuse.
