Here we see a Russian SWAT officer getting grabbed by a zombie as he attempts to flee. He is mere moments away from the infectious bit at this point. Note he has no real weapon of any kind. He is a goner.
If he is true to the narrative form he may hide the bite from his comrades only to turn later and then infect all of them.
Or, there are many more zombie off camera and he will be swarmed and devoured 3 minutes after this picture was taken.
Note the architecture in the background. Say what you will about Soviet era concrete blocky buildings, there are easier to blockade against hordes. Maybe Lenin was onto something...
