This tends to break up the tissue fibres too much and allows the natural juices to be released too quickily. Fry on a very high heat and finishing in the oven will give you a much better tasting cut of meat, especially if you then allow it to sit for at least 5 mins after cooking.
I thought that the majority of the juices are from the fat, which aside from pulverizing the thing, shouldn't be too much of an issue.
Meh, pork is for the days when you're roughin' it anyway :)
