Essays / Need Help on Term Paper Outline on Post 9/11 Discrimination [3]

Hey I plan on writing my first post secondary research paper on Post 9/11 discrimination against Arabs. But I'm having a little trouble on writing a rough outline.. So far I have:

Paragraph 1: Intro
Paragraph 2: Arab discrimination before 9/11
Paragraph 3: Arab discrimination after 9/11
Paragraph 4:??
Paragraph 5: Conclusion

I can't seem to figure out what my last body paragraph should be. Any suggestions? Thanks in advance!
