Stupid to put them under a thumbprint lock. Locks like that have fairly high false negative rates, which are exacerbated by sweat and speed, both of which would be present in an “active shooter” situation.
And cutting the power isn’t an option, since most locks like this are battery-powered. But since the guards aren’t likely to be able to open the locker quickly anyway, it’s a moot point.
Retinal scanner is the way to go... not very expensive and hard to fake... unless you force a person’s face in front of it or take someones eyeball out.
My neighbor who is in charge of all the IT that uses Bloomberg services tells me...that the biometric keyboards they use as mandatory devices on their equipment has to schedule service calls constantly for the units which do not let users access to their systems.
It’s either too swift a swipe, or the user’s thumb is too cold...yada. I wouldn’t trust such a system if lives were on the line. It’s only to make people *feel* as if they are doing something to prevent another Newtown.
