'Smart guns' - an inherent failure
The various 'smart gun' schemes fail on a number of issues, almost axiomatically.
In the case of this fingerprint reader stupidity, these include
1. Increased complexity and decreased reliability... leading to decreased safety for the user.
2. Delay in operation - as noted, this can increase risks to user, and reduce utility.
3. Increased cost.
4. Will not work while wearing gloves.
5. Potential failure of locking / authentication system (may fire anyway), leading to a false sense of security and, likely, accidents.
6. May fail to function for other family members in an emergency.
7. Susceptible to failure due to battery depletion or low voltage, particularly in extreme cold temperatures.
