When Root comes for rescue, she shoots up a room full of hostages from outside behind closed doors and gets more than 2 clean headshots without even seeing what she's shooting at. This would have been nearly impossible to do even if she had a clear visual of what she was shooting at.
Just when Finch and others were about to get executed, Reese and Fusco come to their rescue in the last second dressed as SWAT. At the time, Reese and Fusco were more than a thousand miles away in Colorado so they wouldn't be able to get there in time to make the save.
Besides, they hadn't even connected to Finch in days and didn't have any idea where Finch and others were located so it would have been impossible for them to come at their rescue even if they could magically teleport because they had absolutely no idea where Finch was at the time.

Root steals a knife from Control's pocket and uses it to escape captivity but even if she were able to escape the inner cage within the building, she wouldn't have been able to escape the building that was full of heavily armed guards. There is no explanation as to how she went past those guards without having any weapons other than a small knife.
