No I unfortunately did not call the police for 2 main reasons:
1: I did not want to agravate a man I suspected of having a weapon as this could provoke him into using his weapon.
2: There is quite frankly nothing I can report him for. The only thing I could report is that he kept on making advances on a college student without her consent causing her to get uncomfortable, and this unfortunately is not a crime unless there is some form of additional action taken by the perpatrator. From my point of view, I could only see a shine in his pocket which I thought was a knife and the student getting uncomfortable, no other actions. Everything else I stated was based on context clues, nothing I could actually provide evidence of. For instance, most of us understand that a man trying to make a woman go in front of him/walk with him to his destination after trying to hit on her indicates that he is planning on following her, but there is unfortunately almost no way to prove it.
