& if they did call the cops, will they be sending her a letter etc. my friend was a walmart last night & she took a few things :( she said the guy followed her out & chased her & she ran to her car & took off. the guy was saying "don't trip i'm going to call the cops" & she is not sure if he got her license plates or not. what is the worst thing that could happen/what should she anticipate ? also, can the cops pull her over on the street by her license plate for it ?
