Russia doesn't drone 'suspected' terrorists based on their meta data.
From Wikipedia's article on the Second Chechen War:
> According to the 2001 annual report by Amnesty International:
>> There were frequent reports that Russian forces indiscriminately bombed and shelled civilian areas. Chechen civilians, including medical personnel, continued to be the target of military attacks by Russian forces. Hundreds of Chechen civilians and prisoners of war were extra judicially executed. Journalists and independent monitors continued to be refused access to Chechnya.
Have a read:
So, yeah, I am fairly familiar with it.
And let me tell you, you are not even slightly comparing the same things.
Better comparison to drone attacks on terrorists is killing of Dzhokhar Dudaev by laser-guided missiles in 1996 and, possibly, killing of Shamil Basayev in 2006.
