Because people assume that email is private -- and there would need to be some sort of good reason that you get an FOIA request. So in normal circumstances when you write to your elected officials you want them to handle your concerns with discretion -- not "John Smith thinks x and he lives at y address and z@yahoo.com is his email address."

What evidence is there of an infinite universe that had no beginning?
Bear in mind also that if an infinite universe exists, which had no beginning, then light would also have had infinite amount of time to travel to here from absolutely everywhere else, and although the intensity of radiation that reaches a point is inversely proportional to the square of the distance to that point. the volume of space that is an average of some given distance away from a point is greater than an amount proportional to the square of the distance from that point, and so the number of things in that volume which produce radiation at that distance would be be correspondingly greater, more than cancelling out the inverse square relationship to the intensity of radiation reaching a point some fixed distance apart. Every point in the universe would be perpetually saturated in radiation that is reaching it from every other point in the universe, infinitely far away, and certainly things like life bearing planets could not exist.
Critical observation suggests that the universe is finite.
This is known as Olber's paradox, and it is not valid for expanding universes where red shift reduces the wavelength of light from distant sources until it drops below visible wavelengths and there ends up being an observable horizon, even in an otherwise infinite space and unbounded lifetime.
Although your point about distance and volume is wrong for other mathematical reasons. The number of light sources expands as the square of radius, not volume. The *total* number of sources is proportional to the cube of radius, but that's double counting. The volume includes close sources previously counted, plus the new sources being added as radius increases. Olber's paradox doesn't rely on that error in math.
Agreed. In the end - even if they are off by a factor of ten - it still gets us plenty of life in a finite universe. There may be infinite space but we have a start and finite velocities so we don't have an infinite universe as that volume is finite.

Submission + - "Advanced Life Support" Ambulances May Lead To More Deaths
HughPickens.com writes: Jason Kane reports at PBS that emergency treatments delivered in ambulances that offer “Advanced Life Support” for cardiac arrest may be linked to more death, comas and brain damage than those providing “Basic Life Support.” "They’re taking a lot of time in the field to perform interventions that don’t seem to be as effective in that environment,” says Prachi Sanghavi. “Of course, these are treatments we know are good in the emergency room, but they’ve been pushed into the field without really being tested and the field is a much different environment.” The study suggests that high-tech equipment and sophisticated treatment techniques may distract from what’s most important during cardiac arrest — transporting a critically ill patient to the hospital quickly.
Basic Life Support (BLS) ambulances stick to simpler techniques, like chest compressions, basic defibrillation and hand-pumped ventilation bags to assist with breathing with more emphasis placed on getting the patient to the hospital as soon as possible. Survival rates for out-of-hospital cardiac arrest patients are extremely low regardless of the ambulance type with roughly 90 percent of the 380,000 patients who experience cardiac arrest outside of a hospital each year not surviving to hospital discharge. But researchers found that 90 days after hospitalization, patients treated in BLS ambulances were 50 percent more likely to survive than their counterparts treated with ALS. Not everyone is convinced of the conclusions. “They’ve done as much as they possibly can with the existing data but I’m not sure that I’m convinced they have solved all of the selection biases,” says Judith R. Lave. “I would say that it should be taken as more of an indication that there may be some very significant problems here.”

Submission + - Big IT vendors mostly mum on commercial drone plans (networkworld.com)
alphadogg writes: Word that the Federal Aviation Administration might take a very hard line on commercial drone use has those with designs on such activity nervous. But as for big enterprise IT vendors, it's really hard to tell what they think because they're keeping any plans in this field very hush-hush. More consumer oriented companies like Amazon, Facebook and Google are active, but companies like IBM and HP are quiet, while Microsoft affirms it has nothing doing. A former FAA lawyer says sitting on the sidelines even during this unsure regulatory period is probably not a great idea. "I have a hard time believing they don't have some sort of programs in place," attorney Mark Dombroff says.
Submission + - Republicans Block Latest Attempt at Curbing NSA Power 2
Robotron23 writes: The latest attempt at NSA reform has been prevented from passage in the Senate by a margin of 58 to 42. Introduced as a means to stop the NSA collecting bulk phone and e-mail records on a daily basis, the USA Freedom Act has been considered a practical route to curtailment of perceived overreach by security services,18 months since Edward Snowden went public. Opponents to the bill said it as needless, as Wall Street Journal raised the possibility of terrorists such as ISIS running amok on U.S. soil. Supporting the bill meanwhile were the technology giants Google and Microsoft. Prior to this vote, the bill had already been stripped of privacy protections in aid of gaining White House support. A provision to extend the controversial USA Patriot Act to 2017 was also appended by the House of Representatives.
