Humboldt State University is investigating the now-viral video of a woman’s arrest after it was posted to Facebook Sunday. Samantha Luna, 20, and her friends were pulled over by cops near the northern California campus. One of them is arrested for sticking her head out of the sunroof and Luna was not happy about it. In the video, she asked the cop why he was being rude. When the cop answered back saying it was her disposition which was disrespectful, the two got into a verbal scuffle. #police #c
