necessary for what? ....in practical terms?
In practical terms, mate long time ago, karakoe host , van full of
karakoe gear in drive, Mrs`s car backed against doors nose against
garage door, CCTV on corner of house, suburban semi, covering drive
into street.
Crims smash drivers window in car roll it back , force van doors and
steal several grands worth of karakoe equipment. Most of it caught on
CCTV.
Cops main reaction is concern that karakoe man has CCTV facing onto a
public street without signage and a contact number.
