Large-scale theft

The decision to make gas retailers responsible for outlets caught selling adulterated fuel is a good start in the effort to crack down on these rackets.

A slew of measures have been announced to this end now and then, but they need to be implemented, at long last, so as to curb the rackets' activities and the enormous cost of those activities for taxpayers. 

It doesn't need a lot of imagination, just political willpower.
