Yeah, true, but man, I see two major storkes against Brashear:
1. She had no reason to go that way at all. I don't believe she was going to Taco Bell or Mel's, or to pick Johnston St. over St. Landry. It's wasted effort and St. Landry is safer.
2. If she were being followed, would she really cross all the way across that road right in front of his grille? Take that risk? Now, if he was hanging far enough back for her to safely do it, then yeah, maybe. But it seems much more logical to me for her to bolt right into the Government parking lot. It's right there, and I bet she knew, from biking a lot, that there was a back way out of the parking lot.
I am really starting to think that she may actually have gone thorugh that parking lot into that neighborhood as part of her planned route... which is why she didn't show up on camera at 224 St.: That changes things altogether. Either she got chased and caught in that neighborhood north of St. Landry, or later on by a DIFFERENT perp near the Cajundome or Blackham Coliseum or on Congress.
