First of it is not a given if you "screw up with a gun someone dies" that is not the only result
Further it is laughable to believe that with facial recognition a "human double-checks" we have seen time and time again that new technology entering the realm of criminal justice can be used to wrongfully convict people at an alarming rate. See Hair and Bite mark controversy or the number of Labs that have been compromised in recent years
The fact is that a "humans" that are suppose to be "double checking" do not in reality, if the computer spits out "Well the computer says it is person X" that is what the Jury will hear, and the Jury will not question the technology and the person will end up in prison until such time as someone like the Innocent project comes along to invalidate either the technology on the whole or the application of the technology

You have too much faith in humanity: a lot can be, and will be done "because the system says so". Nevermind integrators who will create processes that assume recognition is 100% correct "Yes, I know you're not the wanted criminal, but now that I have tagged you, I have to take you to the station and process you out...Monday morning because that's when Jim is in"
If you screw up with facial recognition a human double-checks and nothing happens.
Scissors are dangerous but we don't regulate those either.
