LogicMan, I don't mean any disrespect.You are trying to do something all too common in our society.
You are building your argument based on labeling something and putting it in a simple box.Its just too flawed to continue.
I'm not going to do it for you,you have to do your own research.Go to the Sierra,Nosler,Speer,Barnes,and Hornady websites and check out how many .224 bullets are available,what their design charactaristics are.
To discuss the AR-15 bullet" is something like labeling and boxing "Native Americans" or "Women" or "White Males" into one monolithic group.
I can assure you within that box will be subsets and individuals who will invalidate any conclusion you may come to...but that does not deter media or politicians.
Edward Abby points that out in his book "Desert Solitaire"
The other problem with your pursuit :
We do have a problem. What greater way to terrorize any people,USA or elsewhere, than a mass killing at a school?
Per Rahm Emmanuel's doctrine of exploiting crisis,the media and political exploitation of pain and emotion begins while the fallen are still where they fell.
Its cynically exploited. The targets?
The 2nd Ammendment,the NRA,Gun Owners Gun manufacturers.
None of those,nor the AR-15,are the root cause ,and no action on any of those will remedy killing.
And I'm recognizing a trend.
Fairly new members with low post counts starting discussions such as this.
With a little orchestration,the discussion will polarize.
And then the posts take on the tone" The status quo you know is untenable.Compromisei is unavoidable. You must concede common sense gun safety measures. Resistance is futile.You must assimilate"
Sorry ,but my robot is saying "Danger Will Robinson"
I'm feeling like I am being mined for ore for the opposition. Trojan.
LogicMan,..I forget where to look them up,some fed gov website.
There are stats on homicides. If you lump all the AR-15 homicides in with all the other long gun homicides...rifles,shotguns,etc,by far,fists and feet kill more people.
I also can't say my source or an exact number,but gun homicides are way DOWN,more than 50%,over the last 15 years or so.
Now,the Doctors who ,understandably,are troubled by ANY high vel rifle wound,not AR-15 wounds,
I wonder how the stats work out for the number of people killed by our health care system versus firearms?
