Actually, according to the study linked in the original post, one in eight officers shot in the line of duty is shot with a weapon taken off an officer (themselves or another officer).
That is because officers are known possessors of high quality firearms, and targets for those who not only have authority problems, but see them as an easy source for a gun. Officers also live in a world where almost daily confrontations exist, their frequency rate of violent encounters is stratopheric compared to the average citizen. That results in adrenaline addiction and their short life spans. Many pass away before age 60, same as NFL linemen.
Because officers are targets, more of them carry secure holsters to prevent gun grabs, and they get a lot more training in that area, plus carry close quarters backups to add more redundancy.
Expanding smart gun technology to the public, tho, is an exercise in controlling the citizens ability to carry a working firearm. If the smart gun is always disabled within a 50 meter radius of a police officer wearing a transmitter to disable it, their level of safety goes up. They can respond without as much worry there are ANY working firearms within eyesight. Entry team searches would be much less problematic if the citizens inside can't shoot back.
Long run, we become disarmed and can't resist other depradations on our Constitutional Rights. It's just another prong in the Administration's efforts to make gun law where none existed. It consumes more resources in fighting it, like a two front war, and that creates better odds any other measure does slip thru. It's domestic swarm terrorism against the citizens. BTW - when the opposition labels us with a epithet like "domestic terrorist," it's usually because they are actually DOING it. That's why it comes to their lips so easily.
So, Harry Reid, who would be "in the know" about the Administration's campaign against guns, is actually telling us how it's going to work. Create a lot of incidents and blanket us with little assaults on our rights to keep it in the headlines, all the while pointing the finger at gun owners as the cause.
Let NO crisis go to waste.
Guns that can be used against officers and their legal owners are now an evil problem that must be fixed. Much like cars that can't brake themselves because the driver is too distracted to pay attention to the road. The machine isn't really the problem, but inventing mechanical morality for them makes it seem as if somebody is fixing the problem.
What fixes the problem is fixing the operator, which isn't seen as a long term solution when the government doesn't want any at all. Invent gizmos, don't suggest training as the answer.
