"Can cops really just come in your house anytime they want - anytime of the day?"
Jesus Christ...
The answer is yes.
Police now have the permission of the Courts to enter your home at any time of the day or night, spank your children, kick your dog, drink your beer, eat your honey ham, and make films of you and your Mrs. making whoopie so they can sell it on the internet.
Oh, they can also slap you around, empty your wallet, and take an upper decker in your hall bathroom and you are required, BY LAW, to scream at the top of your lungs "THANK YOU FOR MAKING ME YOUR BITCH SIR, MAY I HAVE ANOTHER!" while drizzling chocolate sauce over your head and hanging marischino cherries off your nipples.
Oh, and while they're on the way out your door, they can also cut nasty greasy chili dog and beer farts, and the penal code now requires you to breathe deeply and compliment the officer for ordering extra onions, or you can be charged with a class 1 felony.
I swear some of the people here are so blisteringly paranoid that it's not even funny.
"My God the cops were on my street! I bet they were spying on me!"
