One morning my wife complained that someone had parked a car in our driveway, and it was in Park, couldnt be moved.
So I checked the registration. Rental car. Noticed on the right seat an interesting couple of pieces of paper: on it were the addresses of many engineers / midlevel managers in Santa Clara valley companies.
Also on it were contact names for the "Reversal Engineering Institute" with an address in some unpronounceable city in China. And similar places.
Some sort of industrial spy had parked in my driveway. But I didn't know where he was, so I walked in to call the tow truck.
Just then my wife yelled at me, and I came out to see the guy getting into the car after having walked over from my new neighbor's duplex, where he was visiting them (I had only checked with the front people, who were not Chinese).
I wasn't very friendly. But he just ignored us, got in his car and backed out.
Tall well built guy, gave me a look of so-what, he didn't give a crap.
Here on a mission, he was just making the rounds.
But just remember, we need immigrants, and we are a nation of immigrants. Repeat that over and over again until the alien armies show up smirking....and no resistance is allowed.
The Russians and the Chinese have tens of thousands of engineers in American companies, some with security clearances. They work on all of our advanced technologies.
I know a rabid Islamic extremist with a security clearance working with our nuclear triggers. I reported it, no one cared.
