I think we couldn't categorise a whole countries' population as 'un/trustworthy'... I mean, I've seen people from the United States being rude, throwing litter in the streets etc... but I've met a lot of nice people. A couple of years ago, a Finnish tourist broke a Moai's ear in Easter Island to take it home as a souvenir. I do know Finnish people aren't all like that. A Czech tourist set a forest alight in the south in a national park, but again all Czechs aren't like that.
My point is, I couldn't say that the Turkish are untrustworthy because 10 defenseless women were sexually attacked by a bunch of arseh*les, because not everyone in Turkey does that.
And when I said that the US is an untrusworthy country, I meant that because of what its government has done down the years, because hell yes they've messed around overseas (My own country being included in that lot).
