Dear Sir/Madame:

1. Thank you for reading and commenting.
2. Please watch the video attached at the end of the articles. I am stating what happened on site as confirmed by the live video. Other videos are available on line. The police does not move during the attack as you will see. The reason is unknown. They are capable of stopping it.
3. Contradicting data (20 vs. 100) comes from different sources. I just quote them to show the discrepancy. I can not estimate the number of people based on what I see.
4. The students are protesting hate speech according to the students.
5. Your choice of articles to comment on and the certain language patterns suggest a possibility of trolling and make me uncomfortable therefore I will not engage in this discussion.

Best regards.
