Damn, fellas, guess I should have posted that in purple.
FWIW, I'll fully cop (see the pun there) to not knowing the situation inside the police car, and I wouldn't say jack about that happening when it's obvious the officer is on a run, as posted in Frank's response. I wouldn't say I'm "100% ready to try, convict and sentence the officer," either, more likely, I'm 100% ready to mumble under my breath, "What's that all about?".
In direct response to the bold above... I'm talking about normal driving speed before and after the light, tooling down the center lane of US 40. Not passing any cars, no heavy acceleration after crossing the intersection, no indication at all of a need to not sit through 2 minutes of stoplight.
If Mr. Stein, or Mr. Still and Mr. Blue above can fill me in on how that would be warranted, I'll gladly sit back with a nice cup of STFU.
Honestly? I have no answer for you. I'd never do that, FWIW. I think we should should be held to a higher standard. Unfortunately, being human, and subject to human failings, sometimes we miss the mark.
