Journalist Anna Politkovskaya, killed in 2006 in what appeared to be a contract murder.

Political killings have declined in recent years in Russia, but still tend to blot Russia's image in the filed of human rights. Several recent contract murders have been tied to Chechnyan politics, where complex rivalries have been taken to Moscow in a violent manner.

Now comes the story of an apparent murder attempt that was foiled by police. A plausible suspect seems to be in hand. If so, this gives the Russian government a chance to show its determination to strike back at terror-tactics, regardless of their source.

I am skeptical of assertions that the Kremlin itself has backed such political terror tactics. But now--with a live suspect in police hands--is the time and the chance for the national government as well as the police to demonstrate their true resolve. It also is time for the international community to pay more attention to these matters.
