Europe isn't a single place. Some countries do, some don't. I don't think I've ever heard of a jury trial in Netherland, but France, Belgium and the UK apparently still have it.
Some countries in Europe also don't have the same concept of double jeopardy that the US has and allow retrials even if someone is found not guilty. Off the top of my head, in England you can be retried for murder if new evidence is presented as many as ten times.
