He claimed he was part of it because he wanted to feel like an important person but the fact is he was not associated with NW. I have no doubt in my mind Zimmerman is an annoying wannabe cop that just wasn't able to make it. I have no doubt he was following Martin and that Martin became concerned because some stupid idiot was following him.
Human nature being what it is, that's the most likely scenario.
Also, keep in mind that "concerned" could also just as easily be "afraid for his life."
The problem comes from the fact that the evidence shows Martin then confronted and attacked Zimmerman. This gave Zimmerman the right to defend himself as he saw fit which in this case cost a young person their life.
I'm not sure what evidence you are talking about, but there is telephone recorded evidence that Zimmerman left his truck to pursue Martin before there was any confrontation. While in his vehicle on a personal errand (said he was heading to the grocery store), Zimmerman noticed Martin walking inside the community. Zimmerman called the Sanford Police Department to report Martin's behavior as suspicious, stating "This guy looks like he's up to no good, or he's on drugs or something. It's raining and he's just walking around, looking about" and "looking at all the houses". According to a police report, "there is no indication that Trayvon Martin was involved in any criminal activity at the time of the encounter". While still on the phone with the police dispatcher, Zimmerman left his vehicle.
As far as evidence that Martin attacked Zimmerman...
The Volusia County medical examiner found that Martin was killed by an injury resulting from a single gunshot to the chest, fired at "intermediate range," between 1 and 18 inches according to a forensic expert. An analysis of Martin's body and clothes described the distance as "a contact shot". The autopsy also found that
Martin had one small abrasion on his left ring finger below the knuckle. No other injuries were found on Martin's body at the time of his death.
The autopsy report stated that Martin had trace levels of THC, the active ingredient in marijuana, in his blood and urine, but the THC amount was so low that it may have been ingested days earlier and played no role in Martin's behavior.
Martin obviously had a cell phone with which he should have called the cops for help if he thought Zimmerman was a problem. Instead Martin, being full of testosterone and the tough guy mentality decided to handle it his way.
There's really no evidence at all of that conclusion. Zimmerman's call to the Sanford Police ended at 7:13:41, and at 7:16:11 (2 minutes 30 seconds after the call ended) was the first 911 call from a witness about a fight, and calls for help are heard on that recording. 44 seconds after that, at 7:16:55, a gunshot was heard on the 911 call. A little over three minutes from the end of Zimmnerman's call to police to the gunshot.
Who do you think was up to no good and out looking for trouble... the kid who was walking back to his future step-mother's house (where he and his father had been visiting from Miami for the past 7 days) from the convenience store after buying a pack of Skittles and a can of Arizona Watermelon Fruit Juice Cocktail, or the armed, self-appointed captain of the Neighborhood Watch with 40
suspicious person-type phone calls to the police in recent months, and frustrated cop-wannabe, who claims he was just out heading to the grocery store?
Here's the full transcript of Zimmerman's phone call to the Sanford Police Department's non-emergency number:
Dispatcher: Sanford Police Department. ...
Zimmerman: Hey, we've had some break-ins in my neighborhood, and there's a real suspicious guy, uh, [near] Retreat View Circle. Um, the best address I can give you is 111 Retreat View Circle. This guy looks like he's up to no good, or he's on drugs or something. It's raining and he's just walking around, looking about.
Dispatcher: Okay, and this guy is he white, black, or Hispanic?
Zimmerman: He looks black.
Dispatcher: Did you see what he was wearing?
Zimmerman: Yeah. A dark hoodie, like a grey hoodie, and either jeans or sweatpants and white tennis shoes. He's [unintelligible], he was just staring...

Dispatcher: Just let me know if he does anything, okay?
Zimmerman: How long until you get an officer over here?
Dispatcher: Yeah, we've got someone on the way. Just let me know if this guy does anything else.
Zimmerman: Okay. These a**holes, they always get away. When you come to the clubhouse, you come straight in and make a left. Actually, you would go past the clubhouse.
Dispatcher: So it's on the lefthand side from the clubhouse?
Zimmerman: No, you go in straight through the entrance and then you make a left...uh, you go straight in, don't turn, and make a left. sh**, he's running.
Dispatcher: He's running? Which way is he running?
Zimmerman: Down towards the other entrance to the neighborhood.
Dispatcher: Which entrance is that that he's heading towards?
Zimmerman: The back entrance...f***ing ____ [disputed/unintelligible - either "coons" or "punks"]
Dispatcher: Are you following him?
Zimmerman: Yeah.
Dispatcher: Okay, we don't need you to do that.
Zimmerman: Okay.
Dispatcher: All right, sir, what is your name?
Zimmerman: George...He ran.
Dispatcher: All right, George, what's your last name?
Zimmerman: Zimmerman.
Dispatcher: And George, what's the phone number you're calling from?
Zimmerman: [redacted]
Dispatcher: All right, George, we do have them on the way. Do you want to meet with the officer when they get out there?
Zimmerman:: Yeah.
Dispatcher: Alright, where you going to meet with them at?
Zimmerman: If they come in through the gate, tell them to go straight past the club house, and uh, straight past the club house and make a left, and then they go past the mailboxes, that's my truck...[unintelligible]
Dispatcher: What address are you parked in front of?
Zimmerman: I don't know. It's a cut through so I don't know the address.
Dispatcher: Okay. Do you live in the area?
Zimmerman: Yeah, I...[unintelligible]
Dispatcher: What's your apartment number?
Zimmerman: It's a home. It's 1950... Oh, crap. I don't want to give it all out. I don't know where this kid is.
Dispatcher: Okay. Do you want to just meet with them right near the mailboxes then?
Zimmerman: Yeah, that's fine.
Dispatcher: All right, George. I'll let them know to meet you around there okay?
Zimmerman: Actually, could you have them call me and I'll tell them where I'm at?
Dispatcher: Okay, yeah. That's no problem.
Zimmerman: Should I give you my number or you got it?
Dispatcher: Yeah, I got it [phone number redacted]
Zimmerman: Yeah, you got it.
Dispatcher: Okay. No problem. I'll let them know to call you when they're in the area.
Zimmerman: Thanks.
Dispatcher: You're welcome.
