No – not DNA.
“Digital” evidence. It comes from the home computer, credit cards, cell phones, iphones, licence plate readers.
There is no magic in these techniques. This is the American police state in action.
Sometimes, you’ll read about a robbery where the cops just virtually drive right to the right suspect’s house, with no investigation. That’s license plater readers and traffic cameras being used.
They want to develop facial recognition better. That’s why they…..….. hound you now for new licence pictures and for your not to smile. Then they can get a “hit” each time you pass a camera. This tech was originally from casinos.
It is hard to find good textbooks in this area. The technology is rapidly advancing. Many areas are filled with cameras. I’ve seen them in city parks, near schools and government buildings. Private businesses are now allowing the police to “wire in” to their cameras.
All cameras, no matter the size, need two things: a power cord and a video out cord. Look for these and you will find them.
WN had a real shot until the early 1980s. Today, the American police has raised the threshold for getting away with it. To go clear, without getting lucky, is “nearly” beyond human ability.
This is why serial killers have vanished. There’s less direct action. But you’re not safer….because the real criminals today work for the government. Just like the third world, the people find themselves between uniformed criminals and non-uniformed ones.
The one saving grace is that the money can’t last forever. There is not enough cash around to wire up the entire US.
