"Thousands of people swarmed Tegucigalpa's airport Sunday in a raucous and sometimes violent cry to demand the return of toppled President Manuel Zelaya, whose homecoming was postponed when authorities here refused to let his plane land. . . . Outside the airport, soldiers and police in riot gear formed a human shield around the runway and the military used tear gas to break up rock-throwing protesters. One man who tried to scale the security fence was shot in the head."
Talk is cheap and easy. But, in foreign countries, the protesters we encourage get killed. If we're not going to back them up, we need to shut up.
