This is one of many incidents that are running rampant in California. Although California isn't the only state that is having issues, so far it is the most publicized. I like this video that Russia Today (RT) posted in regards to the incident.
It is definitely a crazy state of affairs. Do the police realize that in a new world of social media to always assume someone is watching what you do? Do they learn from each others mistakes?
N.W.A is probably making a killing on downloads for "F*ck tha Police" right now....
