The crime happened at night I think. There are policemen patrolling the surroundings of my University in civilian clothes and concealed weapons since it's a bit dangerous outside in my country. Also students are usually children of high ranking officials and businessmen since it's a top uni.

Their duty only encompasses from the 6am to 6pm I think. Most likely the same for the policemen patrolling the convenience store. Also since it's just a convenience store, I guess the patrolling wasn't that frequent or was only for a short time.
