"But out on patrol, Beurstraat police are still confronted by the sight of people doing business with hookers, getting stoned and public drunkenness.
Any one of these activities could get you arrested in most other European capitals; but here in Amsterdam, tourists are actively encouraged to get down and party. Police officers are only human, the urge to join the fun must be enticing. "
also bullshit...prostitution is legal in many european countries. Germany is relaxing it's policy towards pot as is Denmark. If you've never been to a German bar it's an experience unto itself..these guys can down more liquor than a whale can sea water. Berlin is party central....I've seen people having sex in bars there as well as in France. Berlin has an entire festival devoted to sex and drugs in the spring...called the lovefest parade.
here's some pics:
