I guess no one dares to harm on American on foreign soil nowadays. A few years back in Romania a drunken marine driving his car, killed a civilian. He was immediately sent to the US, and cleared.
Just shows that if you're American with enough money you can get away with anything. It has been happening for years.
The dignity the Kercher family have shown compared to the way the brash gobby yanks have behaved speaks volumes. If the useless, lazy Italians had done their jobs properly in the first place this wouldn't have happened.
My thoughts are with the Kercher family at this time. My heart goes out to them.
