I have a master security licence in NSW endorsed by the police and yes we've designed, installed, maintained security in public/govt/diplomat homes and offices. Security as in every day security in public premises are handled by private firms. This includes law enforcement security. Police have security firms look after stations. We've even done security installations for the defense force, airport, navy. However govts are poor, still a public povo service, most of our ludicrous security contracts are Arab clients who have so many investments going in Oz like hotel chains in the middle of nowhere, private airstrips, private islands I kid you not, my dad designed & inatalled for a private island. Engineers in the army/police are young and stupid. Do you honstly think the govt leaves such matters to inexperienced dunderheads? They don't. So what in goodness names does this have to do with devolution?
