However when correctly printed and supervised, it can work for many rounds.

Consider that nearly every type of wood is stronger than this plastic and then revise your answer.
There are far easier ways to make much stronger non-metallic tubes than using a 3D printer anyway. Think of fishing rods or carbon fibre reinforced plastic tubing in bicycles for a start - no polymer printer can make anything close to the strength of such composites that can be as easy as winding a thread onto a stick in a tray full of resin.

What's your basis for that claim?

Zimmerman also admitted on the phone to breaking off pursuit.

In Australia some years ago an enterprising soldier found that a spent missile tube could neatly contain three cans of beer, and they became popular items after that. About two years ago the media and/or a state police force made a huge fuss about them as if they were WMD's and there was a crackdown on these harmless objects (without the missile it's just a tube) and a lot of effort went into tracking down how many had been discarded and where they were.

Since you insist on playing this stupid game, let's wonder what you'd do if your son or daughter was Zimmerman. Sounds to me like you're someone who couldn't make a unbiased decision in that case.

Wood bullets for training? That's what they want you to think. The complete lack of vampires in Israel tells the real story :)

It's evident that you don't understand the issues here. Martin was bashing Zimmerman's head into the concrete and Zimmerman had a reasonable expectation that his life was in danger. There are certain conditions where one forfeits a right to self-defense. Show they apply here. As has been repeated noted, merely following someone doesn't forfeit the right to self-defense.

No. He doesn't actually have that right.

Too bad reality got in the way of that sentiment. Sometimes, circumstances aren't optimal. In those cases, we may be forced to go on "feeling" rather than perfect information.

Still need to be an order of magnitude stronger to be much more than a hand held plastic grenade that just happens to be gun shaped and might shoot something instead of blowing up in your hand if you are lucky.
Also why ever bother with 3D printing of a smooth bore barrel? Carbon fibre plus resin wound on a rod is going to be stronger than anything likely to ever come out of a polymer using 3D printer and is a lot easier to fabricate.

Come up with evidence that contradictions Zimmerman's testimony. Where's the reason not to believe Zimmerman?

We can't just jail people merely because it's in their interest to avoid jail. Otherwise everyone would be in jail aside from the occasional crazy looking for six months of free meals.

So why is getting out of a car "pure confrontation and aggression"?

Intel does currently have two big advantages over ARM. The first is that they are typically a generation (or, at least, half a generation) ahead of other fab owners. This is the same advantage that allowed them to compete with superior designs from AMD for the late '90s: they could get higher clocks at the same power, and more chips per wafer (meaning lower cost). The other advantage is that they are a much larger company and so can afford to make half a dozen guesses about the state of the market at the end of the five-year chip design cycle. They can then have different teams working on chips for those market predictions and only actually ship one or two of the final microarchitectures. In contrast, every ARM chip has to be a success, often for several generations (for example, the new A7 is an A8 with a number of refinements and a lot of tweaking for optimisation and some slight ISA tweaks to make it instruction-set compatible with the A15).

Bullshit. Having your balls squeezed also flies in the face of that "political narrative" yet that's what the TSA is doing.

Unless you live in isolation from any communities, you already live in such a community. People do not universally trust other people unless they have a medical condition or mental handicap. And it turns out that they have good reason not to trust other people unconditionally.

Well, those links do back his observations.

I have a suggestion here. How about you change your mind from "barely give a fuck" to "don't give a fuck" and leave this debate to the grown-ups?
