You have a way of writing where it comes off like you're trying to make it sound much more grandiose and important than it really was. Have some humility and put your accomplishments into perspective. When you talk about being a warrior, it sounds ridiculous. When you're talking about being a protector against rogue employees, I hear cheesy superhero theme music in the background and I do this ->

For all I know, you were the caped crusader for our chicano compadres, but if you were, you'll need to get into details of what you actually did that was of such significance. IMHO, it's not enough to say that you were always vigilantly on the lookout for the misdeeds of unethical coworkers.
From what I read, your main pieces of information you want to get across are:
- You have a passion to help those in the Latino community
- You have an understanding that undocumented Latinos often do not get a fair shake with the judicial system.
- You also understand that many first-generation Latinos are disproportionatly disadvantaged (whether through malice or unintentionally) in a number of ways
So say that. Start with an anecdote, a powerful story of how you realized Latinos were disadvantaged on the aggregate more than non-Latino counterparts.
Then talk about your background with the Spanish language, and your affinity for many of the Latin cultures.
Then talk about your work experience and how this fueled your desire to do more - not only act as a small safeguard and ensuring all customers had an equitable experience - but to become an attorney and act on the behalf of your clients.
You can talk about how this could lead into immigration law, or a thousand different type of government work, or something else I'm not thinking about.
These bulletpoints should frame a much stronger PS. Just get your thoughts down. It sounds like you're trying to edit as you write, which is the best way to make it come out poorly. After it's all done, review it and see if it's saying what you want it to say. After you finish the building, then you can start painting the walls.
