but that does not mean the pros outweigh the cons. It should be noted that much of the legislation regarding this issue specifically exempts police and military from the requirement to have owner authorized weapons. So in many cases the situation you talk about would not happen since the officers gun would still be "old technology".

The technology is just not there at the moment. It's not reliable enough (main reason why police will not accept it) and its quick to deactivate. A modern gun is essentially still electronic free- its all mechanical. Any introduction of an electronic part to a gun (unless the gun was completely redesigned) could easily be defeated by just removing the part. Just open up a modern handgun and see how many parts there are- not many. This is done for a reason- the simpler the design the less there is to go wrong.

I haven't seen one piece of technology proposed that couldn't be defeated with a screwdriver in less than a few minutes
