Hopefully, you will actually put a little more thought into the title of your research paper. For instance - there is no such thing as "police brutality", the correct legal term is "excessive force". Police officer are given legal authority to use tactics that some would call brutal to subdue, disarm, disable, control or take someone into custody. These tactics are collectively known as "arrest control tactics". The agency I work for actually just finished rolling out a much more aggressive use of force system. The previous system we had used for decades, was no longer effective in dealing with persons resisting arrest or attacking officers.
The use of "arrest control tactics" follows something called a use of force continuum.
You might be interested in searching the terms:
- use of force
- force continuum
- deadly force
- PPCT - pressure point control tactics (this is the old system - that is useless in today's more violent society)
- Koga - another system'
- FBI method, another system
- Krav Maga, another system
I believe this will help you create a topic and title for your research.
