Teacher isn't hard enough?

In my science cl, there are students misbehaving and being extremely disrespectful to the teacher and other students. They interrupt ME learning along with the single other person who wants to learn. The teacher just isn't strict enough. She lets gum, cell phone use, swearing, being disrespectful just slide. She never wields her ability to punish those who take away my right to learn. She hasn't issued a single referral, detention, yellow card signing or any of the discipline steps that I think could be issued on a daily basis. What should I do? I know that if I tape the cl, everyone has to know that they're being recorded in CA. What should I do about this?
