I've seen the following videos:
1.) the one with the square - mcgrady's - noticed nothing unusual. Everyone who wasn't HG looked like they were a part of the party scene there, and no one looked particularly up to no good to me.
2.) gas station video: the run didn't look panicked. It looked... incoherent or misguided or.. I'm not sure what I'm trying to say here but it didn't look like a run where she was being followed, in my opinion.
3.) the one at the mall - there is a fat white guy between the umbrellas at the top of the screen who sees her coming, pauses when she passes, and then starts to walk again, behind her. There is a group of 5-6 dudes (Can't make out race) and one keeps looking back. Not sure if they followed her there or were just in the area walking through. Hard to tell.
4.) the one from the jewelry store - this walk looks rushed but I am having the HARDEST time trying to figure out if she's alone or not. And, I see a man walking behind her. Not sure if related.
