The handling of his arrest is unusual. In a case like this, a European Arrest Warrant (EAW) should have been issued, and extradition from the US could have been requested. Instead of using these channels to arrest him, they waited two years. When someone is suspected of causing grievous bodily harm, police waited two years while it was publicly announced that he would be in the same situation nearly every night while he toured the EU and the US. Why would law enforcement not attempt to apprehend this man when he is going to be in similar situations on a regular basis? Seems like someone doesn't believe that the evidence in this case is sufficient.
