Our friend Zissou invited me to join this discussion.
My father invented the Barrett Model 82 .50 caliber rifle and introduced it for sale in 1982. His motivation for designing this rifle was purely related to his hobby of shooting. Though no one realized it at the time, his invention went on to become a useful piece of equipment for our military, and allies.
I was born into this business and this spirit of freedom. I have been designing guns and enhancements to weapons full time since 1996 alongside my father. My motivation is exactly the same as his in 1982. We share a gift for design, and a personal interest in guns and the people who use them for honorable purposes.
On to the topic of "why should anyone own a powerful weapon"
From a practical standpoint, it has benefited our country that free people like Ronnie Barrett, with no taxpayer funding where able to take an interest in guns and later design an innovative new tool to help move us forward. This would have never happened had he been subject to restrictions on things like legal machineguns, "sniper rifles", and the like. Owning and using guns sparks creativity for design, just as a car designer has surely spent a lot of time driving many cars.
That is a logical, practical argument that is easy to understand for most.
What is far more difficult is the sociology, and or psychology that leads to one group of men disarming another group to "protect them".
There has been talk about the true intent of the Second Amendment. Having studied the big picture, and considering the context in which it was written, it is plainly clear to me. The men who formed our government wanted no disparity of force between those who served in government and those who are subject to their leadership and decisions. The final check and balance that protects our consitutional republic from slipping towards other less desirable forms of government.
Fast forward to today. Our society is incredibly peaceful by all standards of the world. Law abiding, respectful people own millions of guns in this country, though most of them never harm anyone. More children are injured by backyard trampolines than an irresponsibly stored firearm.
In some areas of our country crime is a regular occurrence. Some have actually blamed that behavior on inanimate objects, guns. That is far easier than addressing serious problems.
With all that in mind, why would those we have elected to serve, look at the law abiding peaceful group and tell them they need more restrictions on what weapons they may pocess? We know this has no affect on crime (see the results of the 10 year run of the 1994 "crime bill" that banned "assualt weapons")
That is a hard question to ask because the possible answers are all frightening. All of the scenarios point to a sinister motive of the group that wants complete control, un-questioned obediance, and ALL of the power. Why?
Why should some trustworthy citizens not be trusted with with a powerful rifle? Are they lesser humans compared to our brothers and sisters who serve in uniform?
If you don't understand why regualar citizens have the right to own a .50 caliber rifle, please, at least get to know some who do. You will meet some people who have a passion for their hobby, and are generally very patriotic. Many of them like Ronnie Barrett will have a great love for this country and a desire to serve those who risk everything in defense of our nation.
Trust those who are proven to be worthy. Punish people who actually commit crimes, not those who could commit crimes.
