Amazing and disturbing tweet from Fort Hood area. Now with ebonics translation

The Huffington Post tweeted this Twitter search result which shows tweets coming from the Fort Hood area. It's an amazing feed actually. I noticed the tweet above in the feed, and had to pause for a second. So amazing and disturbing. So many levels.

Rough translation:
There's a shooting at Fort Hood, and people are being killed. I'm going to go to Walmart and purchase a firearm in order to protect myself cause I don't want to die. I'm going right now.

Update:

Upon closer reading it occurs to me that he already owns a firearm and going to make sure he has it with him when he goes to Walmart. Yes, I think that's right. So, new translation ...

There's a shooting at Fort Hood, and people are being killed. I need to go to Walmart, but first I'm going to get my firearm to protect myself cause I don't want to die. I'm going right now.
