Danish hash joints and the numbers game

Danish police recently arrested a number of people in Copenhagen who are believed to be behind the mass production of marijuana joints.

The police have said that one man has been identified as the main distributor and has charged him and the other people in question with producing a staggering total of 270,000 illegal joints.

270,000. The mind just boggles at a number like that, so let’s try to break it down a bit, using simple maths.

If we say that these people are working around the clock and on average knock out a joint a minute we can calculate that it would have taken them:

270,000 / (60×24) = 187½ days to produce the joints. That’s more than half a year of no sleep, just rolling.

Makes you hope they had a cigarette rolling machine….

Why robbing banks doesn’t pay (much)

Any would-be bank robber should take a second to study the data kept by the British Bankers’ Association. Now the guys at BBA’s word might not be as good as gold here, as they do have a vested interest in keeping people from robbing banks, but lets just ignore that for a second and take a look at their data, as presented in a recent paper by three economists that managed to gain access to the you can see that there were a total of 106 attempted or successful robberies in the UK in 2007. Britain had a total of 10,500 branches in 2007.

Now, according to the Wall Street Journal, the average haul in those robberies was $31,600. However, a third of the ‘successful’ robbers came away empty-handed. I guess that success counts as getting away for them.

So the average heist was actually $46,600. Except that 20 per cent of the successful robbers were later apprehended.

It gets worse, though (at least if you’re a robber).

On average the robberies involved 1.6 persons, meaning that on average a person involved in a successful heist came away with $19,750. That’s roughly half of the net average earning for a UK worker, meaning that the bank robber would have to take part in two robberies a year to be middle class. Yep, here’s another candidate for the hardest way to make an easy living.
