Not sure if this is a new policy, an overzealous rookie rent-a-cop or a slow day, but I saw the port rent-a-cops that patrol the fenced and non-fenced port zones and the touristic old port driving their truck among the pedestrian and bicycle traffic on the quays and stop old port tourists from taking pictures. I don't know what's going on, but IHMO they are pushing a bit too heavy (especially when one can go a few miles away or across the river and see the same things without being in their jurisdiction).
