Give me a break. After the NATO bombing campaign, returning Albanian refugees & KLA were taking revenge on the Serbian residents of Kosovo. The Germans' idea was for their patrols to be able to readily identify the Serb homes so as to better protect them from the Albanians. As a translator working for KFOR, Ms.Gavrilovic knows that, but has chosen to deliberately mischaracterize their actions.
Putting yellow X made of "police line" tape houses would be indeed a sign of thoughtfulness if the styles of Kosovo Serbs and Kosovo Albanians were indistinguishable by architectural styles.
But they look completelly different. Albanian houses have the look of fortified compaund, Serb houses does not.
Putting a yellow X mark on Serb house is like putting a mark on a black horse to help distinguish it from a white mare.
Since you claim to have been stationed in Kosovo you know that, but you have chosen to deliberately mischaracterize Ms. Gavrilovich's remark.
Don't worry, the truth is coming out.
