My take on the lyrics:
Jail them (or 'dem'), before it's too late
Jail all these back market reprobates
Murder, John public can't buy
Raising the price of foodstuffs too high.

Day after day there's a hue and cry,
They can't buy food at prices too high,
Black market is rampant through rank and file,
The boller(?) profiteering is no this time

No use to lament comment nor wail,
From Ceasar to Ceasar to no avail,
There's every where to be seen,
The law is being contravened,
So the police should intervene-ah

Jail them...

Bush doctors are doing a raging trade,
The charge for their bushes they are not afraid,
Sixty cents for a piece of 'shadow penny'(?)
A dollar for a twig of 'keema weed'(?)
Ninety cents for the lease of 'huzay-ma-ho'(?)
The janbush(?) is going on in front your door
There's every where to be seen,
The law is being contravened,
So the police should intervene-ah

Jail them...


Love the song :)
