You’re not haunted by the war, Dr Watson. You miss it.

He closes his eyes. He closes he eyes when he squeezes the trigger. Captain John Hamish Watson was not even looking at what he was shooting, and he still hit it.

not that i don’t agree that John is a badass 

but in Lestrade’s defense, the police in the UK aren’t allowed to carry guns normally.  it has to be for for a special reason.  

if he has the gun that means he’s had special training and Mycroft most likely let him have the gun for the case.

Lestrade unlike John is not used to firing a gun specially at a moving target.

so yes, John is a badass, he can shoot anything but it’s not Lestrade’s fault that he’s not John
