That would have helped my friends. They had several dozen used bicycles they were shipping to Africa sitting behind the container they were loading. Some idiot came along and threw them in the back of a truck and took off. The police traced them to a metal recycler which paid the guy like $139 and immediately shredded all bicycles, so by the time the police got there, there was nothing to recover. Sigh. Had another meth head that took a hacksaw to a $30,000 bronze statue to sell as scrap for $100. It's depressing that morons are willing to do so much damage for so little gain; I'm sure the people that have had the copper stripped out of their houses feel the same way.

William Shatner? Is that you? I recognize your speaking/punctuation style!

AT&T complete list of customers? Yeah, that will REALLY narrow it down!

Fiber optic cables are glass in a plastic sheath run through a PVC pipe... other than the connectors, I wasn't aware there was any metal involved. Are the morons stealing metal to buy meth really that stupid? (By this way, this is yet another reason why fiber is superior to cable -- used fiber optic cable has very little resale value, but used copper becomes more precious every day.)

ISIS doesn't use Twitter to communicate amongst it's members. It uses Twitter to recruit new members. And so far, it has been surprisingly successful at doing so. What need to stop doing is attacking Islam in general in response to the atrocities committed by criminal. Attacks on Islam is the jihadist's best recruiting tool, to the point where I no suspect many of the people bad-mouthing Islam may in fact actually be Jihadi recruiters.

No, they can also continue kidnapping young women to hand out to their soldiers as sex slaves, which as near as I can tell is their primary recruiting tool. I appreciate the air strikes, but air strikes alone don't solve the problem. What is needed is a regional coalition to put boots on the ground. The country in the best position to put boots on the ground is Iran, which may be why we are currently attempting to cozy up to them -- we share a common enemy.

If ISIS, Boko Haram, and Al Queda aren't stopped now, pretty soon they'll all be fighting each other... the plan each one has to be the only Muslims to establish a global caliphate are pretty much mutually exclusive, don't you think?

Yep, Karma's a bitch, isn't it?

Mr. Yee, what about banning pressure cookers? We've just proved even morons can make effective explosive devices out of pressure cookers!

... but they'll have to walk barefoot across a huge room with a floor littered with thousands of loose legos first!

I'm pretty sure black power is just sulphur, charcoal, and saltpeter... and that's without bothering to even google the recipe. People have been casting their own bullets out of lead for hundreds of years now. Machining your own brass shell casings is probably more trouble than it's worth, but there are literally billions of them already out there, and they are generally reusable. Hardest part to make is the primer, but understand those are made out of mercury fulminate, which my dorm mate made in his room in college -- and he was a computer scientist, not a chemist. Wan't to skip all the complicated stuff, go back to using single-shot muzzle loaders, preferably flintlock. 200 year-old technology pretty easy to replicate today. And most likely pretty easy to make one that won't trigger a metal detector.

Mostly plasting, except for the metal end carrying the primer, and of course the metal shot inside. But yes, I'm sure somebody has by now made non-ferrous ammo to go with the non-ferrous guns that have been around for a long time. In fact, ceramics are pretty strong now. I wouldn't reuse them like brass shell casings, but I'm pretty sure they could be designed to survive a single shot.

Zip guns are single-shot. Printed guns take clips and are multiple shot until they jam, which should happen within the first few clips. Both are fun toys, but nothing I'd bet my life on when a Glock or Walther PPK are still relatively cheap.

Nobody buys a $1000 3D printer to make just one item, just like nobody plants a field of marijuana to get just one joint. Yee doesn't want the people that now go into the drug business to go into the gun illegal gun parts manufacturing business. But Pandora's box is already open, and stuffing everything back inside is now impossible... existing 3D printers can be used to make more 3D printers, in fact most 3D printers come with blueprints to replace easily warn parts and recommend that he first thing you make is spare parts!

Kind of like Restraining Orders... because obviously anybody planning on breaking the existing laws against assault and/or murder is going to totally change their mind when a judge says coming within 100 yards of their intended victim is now against the law!
