I remember that, It was a funeral. From memory they (the bikies) applied for a permit, or got permission, resulting in them getting an exemption from wearing a helmet. I am not sure who they applied to whether it was the Govt. or the Police Service.
I remember there was a lot of press hype over it blowing it out of proportion.
Chev4evr appears to be a copper perhaps he could shed some light on this?
