America as a country is a little different than most countries in Europe. Because of the many different states, you could have a Nevada fighter go over to California and get robbed in favor of the California fighter. The home-cooking isn't a country level thing, it's a state level thing. Texas has some awful home-cooking but New York is generally fair. You can't really group all of America together; that's like grouping Germany's bad decisions in with the UK. You don't typically see home-cooking in most states. That being said, I don't really see a whole lot of home-cooking in the UK either.
In the UK to get a stoppage all you have to do is flurry your opponent up against the ropes. It is a joke.
well just watch haye vs berrett he hit him behind the head and while he was down and it is perfectly ok! other than that its like in most countrys!
