No R-41 your edit is biased. Kosovo is DISPUTE TERRITORY as established across wikipedia. this is not a new outlet to take a [western] side.

"cooperating with Serbian law enforcement? Is it opposing the Kosovo Serb actions " No it is not, and yes it is CLEARLY opposing Kosovo Serb actions . there is NO doubt on that...if there was there would be no such article.(  ).
