Like I already said, you don't know what is going on in California or Colorado except what you read.
I've known many people who were following the law to the letter, and still got busted. Pigs lie constantly, and the media repeats their lies.
In my case, I was raided simply because I am an outspoken advocate for MMJ patient rights. The pigs wanted to take me down, and they did. They broke in my front door at dawn. I was not breaking any laws, and the pigs lied to say I was, and they charged me with 7 felonies. They also stole everything I had, including the money that I had left after selling my house.
I can tell you many more stories of corrupt and sadistic pigs, but I don't want to type a book.
One more though, a good friend had a grow house, everything completely legal, and he was allowing two women to live there for free. One morning the swat pigs broke in, and held guns to the heads of the women while they stole all of the plants and bud. Then the pigs left, and were not heard from again. No charges were filed, no arrests made, and the grower whose legal papers were posted on the wall, never heard from them either. He was just ripped off by the pigs.
