Orangello, while there is validity in your post, please consider this...
Just as with any other criminal undertaking or enterprise, there are different varieties of burglar.
There is the smash and grab, the home invader and the pro burglar. Frequently, burglars will gain entry--not necessarily by smashing in the front door, but by tricking a lock or finding an unsecured window. If they gain entry through a door, they will LOCK THE DOOR BEHIND THEM. Why?
Because if the police do show up, all they have to do is to lie low and still and hope that the cop is lazy or complacent enough to check the doors and drive off. That's why when we respond to a burg call, we set a perimeter and wait for the owner if we cannot find a point of entry.
So, now you have arrived, and my partner and I are there. You come up with your holstered handgun, and say, "Thanks, but I'll clear my house myself."
What you--and we--don't know at the time is that the person hiding in the house is a (example here) two-strike loser, convicted of violent felonies and looking to feed his habit. He knows that if he gets caught, it's his third strike and he faces a life sentence.
So, knowing that this is a possibility, we tell you, "Hey--I know that you're kinda bent out of shape over this. But give us your keys, and wait out here. And, while we're at it, I'll have to ask you for your handgun as well. It's only temporary--you'll get it back after we come out."
Why are you disarmed? Because human nature is a funny thing. We place great value in our homes--not monetary, mind you--but our home is OUR HOME, darn it, and who is this jerk that just broke in to MY HOME?!? I don't want you to lose your composure and run up to bust a cap in the jerk who broke into YOUR HOME.
Here are the other reasons.
We are trained to clear houses. We don't know if you are or not.
We are there to protect YOU. It's our job.
You would be going in with one handgun. That's it. We're going in wearing body armor, and toting 5.56mm carbines with weapon lights--and maybe night vision, as well.
(At any rate, before we go in, we have notified Dispatch, and there are probably a few ore units that have quietly rolled up. They're ready to come in as back up if needed.)
And--if you're worried about what might be in plain view, it's simple--don't do anything illegal, and you don't have anything to worry about. The bottom line, though, it this--when I do a building search, I'm looking for contrast and shadow; movement where there should not be any; I'm listening for ANY noise, and watching for lights. I'm looking through a weapon sight, and I'm concentrating on getting the burglar OUT of your home.
(Of course, if we KNOW there is someone there, we aren't going to play games with them--K9 is a radio call away. Let the puppy play a bit.
