Nope sorry, fail to see how Britain is anywhere near as dangerous as somewhere like, South Africa.
The Daily Mail, like a lot of fellow red top newspapers, and some other papers, like to keep the population in a state of fear. They're opinions, and views in the paper are often accepted and taken on board by the readers, which in turn delivers what they want.
In a odd, way they're killing independent thought, and keeping the people where they want them.
Britain, has a very low reported crime rate compared to places in South America, America, Parts of Europe. We should consider ourselves lucky to live in a fairly peaceful country. The unreported crimes in this country and probably higher then they should be, due to papers taking away the importance and role of the police.
However, they're pitiful compared to the unreported crimes, in Johannesburg alone for example.
Going out on a night out in England, hey might get in to a fight, but thats more due to the drinking culture, that has been accepted by many papers, where people will drink to excess and fight. Fight, Punch, kick.
You don't even have to be on a night out with friends in some parts of the world, you'd be killed regardless, of time of day, who you're with or who you are.
