How exactly staging the murder by someone else other than would-be killer helps with catching that person?
Imagine you're that killer, and you see the news about your future victim. He is dead. What next? Go and kill him again, or pack your stuff and go for a few months vacation in Mexico.
Also, I guess anyone with facebook page and few TV appearances is a fierce Putin critic now. MMO-C regulars, beware, you might be next. But don't worry, we already know who to blame, even before actual murder .
