"I can't go out."
Those are the first words from the embattled Ferguson cop who shot unarmed Michael Brown.
In a text sent to his friend, Jake Shepard, officer Darren Wilson writes that he is under 24 hour police protection.
The text was sent to Shepard after he appeared on CNN defending his friend of 14 years.
Shepard told CNN, "He never talked about minorities, I mean, he was of moral virtue where he would never bring something like that up."
"The support is really keeping me going during this stressful time," Wilson wrote to Shepard, according to the just released text.
"Just stay safe. I appreciate all you have done. It means a lot thank you," texted Wilson.
Meanwhile, what does officer Darren Wilson's body language reveal about his mindset after he fatally shot Michael Brown?
The first thing body language expert Tonya Reiman noticed was the fact that Wilson's palms are face up.
"Here, when somebody raises their palms like that, what they're asking you to do is believe what they're telling you," said Reiman.
She says Wilson also shows obvious signs of stress.
"He's slightly hunched over as well. So this is indicative of someone feeling the pressure. When we feel pressure we tend to hunch over and cover up our neck and you can see that's what he's doing here," continued Reiman.
Reiman also noted that the police officer does not stand in one spot.
"You can see his pacing back and forth and that's also a nervous habit we do. We try to get rid of excess energy so we walk back and forth," said Reiman.
The woman who shot the video, Piaget Crenshaw, seemed to agree with our body language expert when she was interviewed on CNN.
"He's just looking over the body just looking baffled and bewildered," said Piaget.
At times, Reiman says, the police officer demonstrates a stance of confidence. His body was turned toward Brown, which she says means he is facing what he has done, and is not showing signs of guilt.
"He's not showing defensive signs in terms of covering himself up. He doesn't seem to be in a position where he feels like what he did was wrong," said Reiman.
We're also learning more about that anonymous call from a friend of officer Wilson who offered the first public account of what happened from Wilson's point of view giving his version of events to a radio station.
The caller contradicts other witnesses who said Brown had his hands up in a gesture of surrender.
Radio host Dana Loesch says she believes the caller was authentic.
"She said that she was a friend of Darren Wilson and so I wouldn't put her on air until I had a phone number that I could confirm. I wanted a phone number. So we got that, made sure that it worked and then I put her on air," said Loesch.
The caller also said Wilson believed Brown was under the influence of drugs.
"He really thinks he was on something because he just kept coming. It was unbelievable," said the caller.
Now the Washington Post is reporting that an autopsy conducted by the St. Louis County Medical examiner showed that Brown "had marijuana in his system."
INSIDE EDITION spoke to pathologist Bill Manion about the significance, if any, of that finding.
"It may make people feel so relaxed that they feel a little bit invincible and out of touch with reality. Not really appreciating the consequences of some their actions," said Manning.

Even so, others believe that even if Michael Brown had smoked marijuana, it still doesn't justify shooting an unarmed man to death.
