Anyway, here they are doing their civic duty by handing in weapons to police during an arms amnesty back in 1979.
Weapons included home-made pistols, lead pipes, maces, spears and axe handles wrapped in barbed wire.
Hamilton Mongrel Mob sergeant-at-arms 'Vini' said they were handing them in "before we get busted".
"Hopefully it's a turn for the better," police senior sergeant Ian Paterson said.
