what does this Lyrical Analysis means?

it's been a week already, feeling weak already
Got me at peak, possibility of what could be
Situation is heavy, I've got to prove
On February 26th I lost my life too
It's like I'm here in a dark dream
Nightmare, hear screams recorded
Say that it sounds distorted but they know who it was
That was me yelling for help when he drowned in his blood
Why didn't he defend himself? Why couldn't he throw a punch?
And for our community do you know what this does?
Add to a trail of hatred
2012 was taped for the world to see
Set us back another 400 years
This is modern day slavery
