I guess they've been heading towards this in baby steps for a while.
I remember back in the 1970's and early 1980's when it was still unconstitutional for them to search your car.
Then the Supreme Court said it was okay.
And in 1983 we were in a car smoking a joint and a cop walked up on us. My then-wife was in the car with all of us smoking and had the pot in her purse. But they couldn't search her purse.
Little by little they have changed that...and it's all in the name of the failed drug war.
So now they have got it where they search us from top to bottom at the airport.
And now they can just come into your house.
