I have no problems shooting anyone in the middle of the night without knowing who it is.
This is a simple, complete declarative sentence. I do hope a prosecutor never gets to use it against you, in court.
As far as pointing your gun and the light mounted, the light does spill. So that is really a non argument. You don't need to point the gun at the target to use the light.
I say it's still an argument. yes, the light does "spill" and you don't
need to point the gun at the target to use the light, BUT people DO, and they WILL.
Even trained police officers sometimes make mistakes and fail to follow their training, what are the odds untrained people will NOT point the gun at you in order to use the light? I'd say slim to none, and Slim left town...
I'm fine with the idea of weapon mounted lights FOR PROFESSIONAL USE. I am very much opposed to weapon mounted lights for untrained (and usually unpracticed) individuals.
The principle is fine, makes sense, can be useful, HOWEVER, in the real world, despite all the safety commands, and even despite some training, you ARE going to have people pointing loaded guns at people, just so they can see them, and some of those people ARE going to have their fingers on their triggers when they do it.
As to the suggestion of turning on the lights as you move through your house, I can see where it could put you at a tactical disadvantage. IF you are in combat. But is the objective to ambush the intruder?? Or is the main objective to drive them away??
Holding the cowardly craven pinned in the icy glare of your weapon mounted light, covered at gunpoint until the police arrive to take them away COULD happen, has happened I would think, but its more likely fantasy than reality.
And the downside is that it could initiate a series of events that otherwise would not have happened.
You, and your family, and your stuff is just as safe if the intruder(s) FLEE. Turning on lights might well result in that, all by itself.
EMP keeping you from turning on the lights? I'd put that pretty far down my worry list. Bad guy(s) cut the power?? possible, but then everybody is in the dark, and unless this is an action movie where the bad guys use night vision, then they're in the dark as much as you are, and will need lights to see, in order to do what they came for, and that ought to make them a little easier to spot...
Me, I use the "hoarder's defense", my house is so cluttered with a lifetime's worth of crap that my heirs will probably find the mummified remains of a home intruder under a collapsed stack of Guns & Ammo, American Rifleman and Shooting Times when they clean out the property after my death....
hmm..now that I think on it, this might explain why some of our cats have gone missing over the years
......oh well, there's no free lunch...
I don't have any weapon mounted lights, in fact, I'm such a dinosaur I don't even have any pistols with rails that would mount them. I just don't think they are a good idea for anyone not a trained professional who's job needs them.
Am not all that sure that they are a good idea for some of the people we consider "trained professionals", either....
