The byproduct of un-policed aggression on the road. The angry jerks are proliferating out there. They are behind the wheel.

Beware, the police cannot police traffic anymore, and if they are in traffic, they let far too many infractions go without bothering to write a ticket. Tailgating, failure to use a turn signal, SPEEDING, Don't they see what we see?

Its all on display each and every day,
but all the cops have seem to have gone away :(
That's all I have to say.
Good day.

Oh please.. cops can't be everywhere all the time.

But this story actually ends with an arrest.. so what's the problem?

Someone had an issue and a cop was there to help.

There's something missing in this story: "A 29-year-old San Jose man was placed under citizen's arrest last week after he had allegedly pulled a BB gun following a traffic incident on El Camino Real in Mountain View"..."The victim reported the incident and using a description of the car Nolasco was driving, Sunnyvale police were able to track down and stop him in Sunnyvale a short time later". Was Noalsco actually placed under citizen's arrest (and by whom?) or was he he tracked down and stopped by Sunnyvale police a short time later? Sounds like maybe there were different sources for this story that might not have been compared before publishing.

Police can't arrest anyone for doing something the don't observe themselves. The Sunnyvale police probably detained him and then the offended individual made the citizen's arrest.
