Halftime show dance waves Palestine/ Sudan flag during performance and gets detained

Interesting that during a super-bowl commercial an Israel flag was shown without issue, but during Kendrick’s halftime show, a dancer held up a Palestinian, and Sudan flag, and was detained and dragged off the field. This wasn’t shown during the broadcast people are just now catching wind of it because people recorded on their phones. Apparently NOLA PD is looking into what they can charge him with and NFL has banned this person from stadiums for life… how is this allowed? Isn’t it freedom of speech or do we not have that if it opposes Israel?
