Julio César Almanza Armas was murdered hours after criticizing the insecurity faced by businesses in Tamaulipas. Weeks earlier, Minerva Pérez Castro was killed for the same reason in Baja California
Business leaders in Mexico are in the crosshairs of organized crime, which has diversified its business activities and now affects all links in the production chain: from agricultural activity to the distribution and sale of products. And those who speak out pay for it with their lives.
Julio César Almanza Armas, the president of the Chamber of Commerce of the Mexican states of Tamaulipas and Matamoros, was killed on Tuesday afternoon after a dozen bullets were fired at his car’s window. His last public words have drawn attention: “Businesspeople are hostages of criminal gangs and extortion has practically become a national sport,” he said on Telediario Radio in Tampico.
You can not machine Sapphire like that, it is too hard, as you have found out the hard way. At the same time, just like glass, it will absolutely break when you throw something soft like lead (bullet) or even water (water jet cutter) at it at high enough speeds.
So if you say this is thicker than normal glass but only rated for something like .22 at best, then I can agree.
I never said it was sapphire, just that the owner was told it was somehow related and an unknown proprietary military material. I have no idea what it was, only the empirical properties and what happened with it. Disputing the empirical is insane. Speculating about what it could have been is the only space to talk about.
The job and requirements were specified in advance. Whomever setup that job presumably did the engineering to know what could be done. It took a bunch of inserts to machine it. It was entertaining to watch. But I was just operating a manual Bridgeport mill and helping when asked.
