I know a few guys have been having a laugh on here, and it has been an amusing read, in all honesty, but if you have some concerns about where you are going there are a couple of things you can do.
You can buy a good guide book. Rough Guide give a good assessment of a country, as do Lonely Planet.
You can also go on the travel forum at Lonely Planet. It will give you a straightforward, no nonsense description of things.
Just Google Lonely Planet and have a look at their forum.
You will probably have your questions answered by reading a few posts, but if you don't, ask the question(s) you have and you will receive your answer.
Good luck, by the way, and please don't be paranoid.
Leave your expectation of life in England behind, and don't worry. Not everyone is a crazed murderer!
