I think we need to keep things in perspective.
It is NOT the case that all Turks are out to take advantage of females from the UK, & women should not be afraid to wear clothes appropriate to being in a hot holiday environment.
Rather, it is that, in common with other areas, world-wide, unfortunately, we have a few perverts pestering women & thinking they can get away with it.
I would suggest that, in the absence of the appropriate police intervention, that women carry Mace pepper spray & be prepared to use it if need be.
Also, if someone would act as a "decoy" & then some likely lads "sorted out" the perv/s it would send out a message to the low-lifes that they could get hurt while pestering women & hopefully this would deter them from their "activities".
This is a situation that should be sorted out by the authorities but if they won't then..........
