I'm going by the transcript not the audio. BBM:
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.
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: OK, he's just walking around the area
Zimmerman:
looking at all the houses.
Dispatcher: OK
Zimmerman: Now he's just staring at me.
IMO, GZ is referring to TM meandering around in the rain. Knowing now that TM had THC in his system, the meandering and staring (in the rain) make more sense.
