I reject your characterization of his behavior. Painting marijuana leaves on your own house does not breach the peace and is not passive-aggressive.
Your post breached the peace...and since it doesn't answer your question without explicitly refusing to do so, this post is passive-aggressive.
It doesn't breach the peace? Oh, c'mon! The neighbors are offended and up in arms -- even the Associated Press is involved, making this a nation-wide story!
And yes, this is classic passive-aggressive behavior. He did it only after he was arrested as an in-your-face symbol of defiance. I'm betting a neighbor dropped a dime on him and he's all pi$$ed off about it.
So, for the second time, you're saying behavior that breaches the peace, is offensive to others, and is passive-aggressive is acceptable?
