In reply to Mike Stretford:
Still not convinced it "attracts coppers in particular" though.
To quote the two articles:
Independent:
"There are about 350,000 Freemasons in England and Wales."
Telegraph:
"The lodge is based at 10 Duke Street in central London, which is also the headquarters of the Supreme Council of the 33rd Degree, one of the most important and mysterious bodies in international Masonic circles, which has an elite membership of only 75 people."
75 out of a possible 350,000 have set up their own profession specific lodge. Hardly disproportionate.
The reality is, it attracts all sorts, some who are policemen, some who are civil engineers, joiners, butchers, etc some of which will also engage in criminal activity, just like any other 'club'.
The real angle being, the police and freemasonry make for great press, resulting in people's misconception it's a society predominantly for bent coppers.
