You have to read the specification closely to get the true idea of how ridiculous this RFP is. To my mind, some law enforcement got ahold of it and stuck in enough requirements, and I think that the DOJ management was clueless enough not to understand, such that its useless as a model "smart gun" and probably impossible to build.
Read this in its entirety:
