Because she probably didn't hear or see it. She likely heard it from her sister, Serino or the FDLE, and consciously or not, it became part of her memory.

Prior to today, according to Selene Bahadoor, she was in the kitchen when she heard garbled sounds. She couldn't see anything looking out the kitchen window. She moved to the screened in porch and all she saw was what looked like arms flailing. She couldn't make out the figures. She couldn't make out what was being said. She only looked out through the sliding glass doors once before the shooting and John Good (witness 6) came out at that time and said what's going on (twice) and then said he's going to call the police. According to Good, at that moment, Zimmerman and Martin were tussling on the ground, with Martin on top of Zimmerman. No one was standing or running at that moment.

The audio of the interviews are much more revealing than the written reports. She also provided a drawing. (Note that it's flipped. She has her house on the bottom left and house with the screened porch and John's house on the top right.)

It sounds like the Bahadoor sisters "pooled" their recollections with each other, and as a result, neither memory is reliable. It doesn't mean either one is lying. More likely they are just mistaken.

An added problem is the inherent weaknesses in Sister W-2's statements. On March 1, Bahadoor's sister told Chris Serino she was upstairs and saw two guys running and saw fists. The blinds were just partially open and it was dark and raining. She walked to another room and heard the shot.

She couldn't provide any identifying details because she only got a quick glance and she had removed her contact lenses.

In a second, follow-up interview on March 1, Serino questioned her about distances. She clearly had no idea of distances, accepting whatever Investigator Serino suggested to her. He asked her how far apart the two guys were she saw running:

Serino: I’m going to step away from you.
About here? [He motions]
A car length? 8 to 10 feet?
About 10 would you say?
10 feet. Ok thank you so much

In another interview on March 9, Bahadoor's sister(W-2) told Serino she was just glancing, and she had just taken her contacts out. It was very dark and she couldn't really see. As to the running, she says she more heard it than saw it. Serino tried to get a direction out of her, but they clearly weren't understanding each other. W-2 either had trouble explaining or Serino didn't understand where her house was.

Serino: Were they running towards your house or away from your house and towards the T or towards the street?
W-2: Towards the T
Serino: So away from our house
W-2: No
Serino: You live in that row on Retreat View, right? If they kept on running, would they have passed your house?
W-2:(Pauses, then agrees.)

Sister W-2 can't answer how far she was from the men she thought she saw. She reminds Serino again she didn't have her contact lenses in. She says they were downstairs, she was upstairs.

On March 20, sister W-2 told FDLE agent Batchelor she more heard than saw anything. She doesn't know what she saw, she didn't have her contacts in or glasses on. But she agrees the figures were moving from left to right.

On March 26, 2012, W-2 is again interviewed by Batchelor. We have no audio, only a cryptic report in which Batchelor says W-2 said the shadowy figures were moving from left to right.

Both sisters were deposed. Selene Bahadoor acknowledged today that this was the first time she mentioned movement "left to right" to anyone but her sister. She also acknowledged that the state had jointly interviewed her and her sister. The prosecutor tried to get her to say no one had ever asked.

Faux pas by the state's attorney: Did he forget to read his own reports? On redirect, he tried to portray Selene Bahadoor as someone who had never been interviewed or gone on TV about the shooting and had no interest in TV fame. Whoops. On re-cross, O"Mara brought out she had been interviewed by Matt Guttman in early March. How did O'Mara know? Selene Bahadoor described the interview to FDLE agent John Bachelor on March 20. While the interview never aired, she told O'Mara she agreed to do it because she wanted more attention to be focused on the shooting.

Selene Bahadoor told Batchelor she talked to Matt of World News. Matt asked her if she knows GZ. She told him she knows George and had spoken to him a few times . Matt asked her if she thought GZ would have done this and she said no, he's always been okay with her.

She tells Batchelor she didn't know Zimmerman personally but remembers him coming around when he was telling neighbors about the Neighborhood Watch. He introduced himself to her and invited her to come to a homeowners meeting about it.

Other items from Selene Bahadoor's 3/20 interview:

She says there was only about 60 seconds between when she saw the arms and heard the shot.

After the shot, she saw the body face down. A cop was there shining a flashlight. More cops came and started doing CPR. It looked like his legs were in a running position (apparently meaning one up, one down.) She remembers a jacket and sweatpants and black sneakers on the body. She thinks the pants were gray. The jacket was reddish color. She didn't see a second person, only the body and the cops. She thinks the hands were "in this kind of position" but she's not sure. (She doesn't say they were underneath him.)

She says her niece and her niece's little girlfriend were in the house but they wouldn't have seen anything in the back at all because they were looking out the front the whole time.

So on 3/1 and 3/20 Selene Bahadoor didn't mention seeing or hearing movement in any direction, either when she looked out the kitchen window or through the sliding glass doors and screened in porch. When she looked outside from the kitchen window, she only heard garbled sounds and saw nothing. If she couldn't make out anything but garbled words, how did she hear movement that sounded like running from left to right? She couldn't have heard it seconds later when she looked out through the sliding doors and porch because John Good came out then, and he says the two males were struggling on the ground. No one was running at that time.

Also, look at the back of her house. There is a screened in porch between the the sliding glass doors and backyard. When she saw flailing arms, she didn't go outside, she just glanced from inside, through the sliding glass doors and porch. What could she possibly see in the dark and the rain, one to two houses down and across the backyard? Yet she thinks she saw the figures with arms standing, while at the same moment, John came out of his house, and says they were on the ground in a stuggle. John was much closer than she was to the figures. And then of course there is Jenna Lauer and Jeremy Weinberg, Witnesses 11 and 20, who were right next to John's house, and they are sure they heard movement coming from the T down past their house towards John's house.

As to Selena Bahadoor's bias, in addition to her saying that she gave Gutman an interview because she wanted more attention focused on the shooting of Trayon Martin, the Facebook curse has struck again. On March 20,2012, just hours before her interview with Batchelor, Selene Bahadoor posted this on her Facebook page.

Shorter version: The state today presented a biased witness who told a brand new version of events. She adopted a version told by her sister, who readily admits she can't see anything without her contacts in, and she had already taken them out. On top of which, Selena Bahadoor couldn't correctly describe Travyon Martin's clothing or its colors just days after the shooting, which she had observed while the cops were shining flashlights on the body. But now she is sure in the pitch dark and rain, in addition to the garbled words she heard that she couldn't make out, she heard running movement from left to right, from the direction of Brandy Green's house up to the T.

This won't be lost on the jury is because Don West did such a thorough job in opening statement. Between his detailed explanation and use of graphic maps, photos and charts, the jury is likely quite familiar with the layout of the backyard area and how dark it was that night. It knows what Witness 6 said, even though he hasn't testified yet.

Shortest version: The state was left standing in the shadows with Selena Bahadoor today.
