Students Oblivious to Danger

Today I came across an article/video about how student's at IU are still partying hard and walking home alone at night - even after the disappearance of a fellow classmate; Lauren Sperier, 5 months ago.  The video/news story spoke about how they had an under cover cop roam the streets at night during the weekend after a huge football game at Indiana University.  The under cover cop was 6'5, masculine and African-American.  Whenever he spoke to students one on one (mostly were intoxicated), the students were oblivious to the fact that there was a camera crew in front of them, and they still acted belligerently drunk. The under cover cop spoke about how students were not even intimated or questionable about him, even though he appeared suspicious. It seemed as though students assumed he was part of the "in crowd" because he had a beer in his hand. Why is it that schools need to show how hard they can party, even though there is still a missing person case that is not solved?  Are the students that oblivious and unintelligent to know how badly they are portraying their school? Not only did they students on camera make fools of themselves, but they made it easy for the publicly to understand how Lauren Sperier was abducted so easily on June 3rd after a night of partying. Students clearly assume that just because they are in a safe town, they are invincible to danger.
