[Flash TV] Why doesn't flash just take Captain Cold's gun away from him?
gpt
The actual reason can be seen in episode 9 of season 2. In the episode we see Snart break into Barry's home and when Barry threatens to arrest him, Snart, says that he's rigged the cold gun to explode if he lets his finger off the trigger. So that explains why Barry isn't able to take the gun out of Snart's hands otherwise the gun would denote and kill him, Snart, and any innocent bystanders who happened to have been caught in the blast of cryo-energy.
