The question has to be asked.

Just what is the current agenda of the NT police?

Their latest campaign to remove cannabis from the market has been remarkably effective.

Darwin is facing its first drought in the twelve years I've been here.

Fortunately for me, I'm just a pot smoker (of thirty years) and not an addict. So I don't feel the need to turn to an alternative.
I'm not happy about the situation, but I will ride it out.

There are many others in Darwin who smoke pot to reduce their need for more harmful alternatives.
Alternatives that are now more readily available than ever before.
The demand for, and supply of speed (more sensationally called ICE by the media) has increased dramatically over the last month.

Others are consuming far greater quantities of alcohol than they did previously.
Some are doing both, a dangerous combination, and a recipe for increased social disorder.

In the last month the NT police have set harm reduction stategies back twenty years. They are the cause of the "ICE EPIDEMIC".

House breaking and associated crime is set to go through the roof.
Just as has happened in all other cities when the same strategy has been employed. Public disorder and alcohol fueled violence will become more prevalent. 

To reiterate the question.

What is your agenda? 

It's obviously not in the best interests of the community.

Who's interests are you acting in? 

Are you trying to increase the demand for your own product by taking out the competition? 

Showing blatant disregard for the wellbeing of the community is something we have come to expect from our "FINEST", so this sounds quite plausable to me.
