My concern is that the semi-auto rifle is getting whittled away and a complete ban is on the horizon.
If by "
getting whittled away" you mean that just one model of semi-auto rifle has become the most popular, hottest selling firearm in the USA and that somewhere between ten and twenty MILLION of them are owned by American civilians, then sure. If by "a complete ban is on the horizon" you mean, some restrictions on such were proposed in the immediate aftermath of the most emotionally wrenching mass murder in our lifetimes -- and were still utterly repulsed federally and in almost all of the states -- then yes.
Otherwise... well, no.
Should a 10 round magazine be the limit a state can impose on civilians?
Obviously none of us here would think so.
With the focus on removable magazines, should there not be an effort to stop this from going any further?
Have you been paying attention to the political fight in the last 20 years? A VERY great deal of effort has been spent in stopping these things from going further. And those efforts have largely worked. Not perfectly or completely in every location, but nationally oh yes.
A semi-auto rifle without a freely removable magazine shows the overall intent of some states to ultimately ban semi-auto rifles.
I don't think there's any question that a near-majority of the dominant political force in a few states would work for a ban on semi-auto rifles. This isn't surprising or new, or very well disguised. I mean, Dianne Feinstein was on television in 1995 saying, "Mr. and Mrs. America, turn them all in." Twenty-two years later we're STILL treading with muddy boots all over her dream.
Using the lack of effort by a state in other areas such as civil preparedness and public safety with regards to transportation, food, water and power can show there are other areas that the state is neglecting and that the focus on guns is counterproductive to public safety. In states, such as California, a major earthquake is not an if, it is a when. Not preparing for a two-week blackout and removing the means such as the semi-auto rifle civilians can use to protect themselves is counterproductive to public safety.
This seems to get a bit muddled. Are we still talking about putting together a federal court case? If so, you really can't mix up issues like whether the state is able to allocate resources for disaster preparedness with 2nd Amendment rights. Some states (presumably) are pretty adequately prepared for the sorts of disasters likely to occur there. Do the citizens of those states NOT enjoy the same rights to adequate modern arms because their state governments are theoretically able to take care of them in crisis situations? I don't think there's sound footing here.
The national guard will not stop looting and mayhem in time. The LA riots showed armed civilians on rooftops of their businesses stopped the LA riots from escalating and spreading. It was not the state nor the federal government that kept the riots in check. It was groups of armed Korean businessmen acting as an impromptu militia. Taking away the semi-auto rifle with a freely removable 10-round magazine is counterproductive to public safety because it would be the most effective weapon that local militias to have in times of crisis.
But looking at photos from the 1992 riots, those shop owners were carrying 1911s, shotguns, a lever action rifle or two, a bunch of other handguns, and I did see one with a Mini-14. I have to assume there were other guns as well and surely a few had ARs, but aside from firing into the air and ground to scare off looters, few if any credible stories seem to have emerged about needing large-capacity weapons to engage targets, nor of any real gun battles taking place, i.e.: rifle-vs.-rifle. So, as an example of where one would have to have a detachable magazine, semi-auto rifle, this might fall a bit flat. (Much as most of us would prefer such, as goes without saying.)
And the government has never seemed to be all that moved by the "citizens defending against civil unrest" idea at all. As obviously unsatisfactory as it certainly is to any of us, the government line is eternally, remain in your homes, don't confront rioters/looters, wait for the police or national guard, store damage is what insurance is for, etc. And truth be told, there's a lot of sense in that. It makes for a compelling argument to us, the gun counter crowd, but doesn't seem to have traction with the government.
The state and national guard can have fully automatic weapons while the civilian populace are limited to semi-automatic.
And doesn't fire them at civilian rioters, unless you see Kent State as a model for how well this can go.
From a hardware perspective, if you're going to use government forces' use of gear in response to mobs and rioters as an argument for what civilians should be allowed to own, you'd be better off appealing for batons, tear gas grenades, and water canons in every household.
