No, it just doesn't fire in those two seconds. You automatically target them, however.
Then wouldn't it just be far easier to switch to deactivating within that time frame then? It removes the a usability of easy mode targeting, as if your target is sitting still for 2 seconds to even LET you do this they deserve their fate, while retaining the role play use of it? From what I gather from this whole removal is solely because there's no want for a button that aim bots for you. Giving it the deactivation method means it can't be used for combat situations at all, and rather for hostage or prisoner situations.
Perhaps, but I'd up the time to three seconds.
