It's been many years since I was actually shooting on a public range.
But when I lived in Norman, I used to belong to Tri-City Gun Club and shoot at their range. Since I didn't go very often, I took a whole lot of guns when I went. Sometimes I ended up not even shooting half of them but it was easier to be prepared.
So in this instance... yeah, I can see getting irritated if the LEO's showed up and wanted _every gun_ collected. So my bolt action .350 Remington Magnum that is still zipped in the case gets picked up by the police? I know, the police are collecting evidence and they have to be sure to get it all. But when there is a fatal traffic accident and evidence that it was manslaughter, they don't "confiscate" every car that happened to be within 100 yards.
Same with my carry gun at a range. It's on my body, its loaded, but it also hasn't been fired in a month or two. You expect me to remove it and hand it over for some undetermined period just because some yahoo picked the gun range to off himself?
I'm not actually saying the police "are 100% wrong" or anything like that. But I think that the police on the ground, at the scene, should be capable of some independent thought. They should be able to make some reasonable choices. If I've got 15 guns with me and half of them are still unfired and they want to take them all away.... it's going to get really tense. Because my assumption is that we have some cops here that just can't resist going on a fishing expedition. That want a chance to make sure all these guns are legal. They want to run all the serial numbers and see if any are stolen. Etc.
Sometimes something really is technically "legal" but it still isn't how things should actually be done. The whole "Protect and Serve" gets forgotten. The fact that you are actually my employee gets forgotten. Treating people like they are innocent until proven guilty gets forgotten. And then you get the Nurenberg Defense, "I'm just going my job. This is our policy." Or my favorite, "It's for officer safety."
