I had the same thing happen to me. I was attending my university and had a pro-second amendment flag "come and take it" with the M4 on it (posted last year on here about it) and the university tried its hardest to get me to take it down. Folks were calling the campus police as they felt threaten that I had weapons in my room. They threatened to search my apartment if it didn't come down. They inspected it and said it did not violate codes and kept telling me to take it down regardless.
So what do y'all think? Is this violating the first amendment? I would say so, but it's New York....what did you expect?
