But Jacques, if you'll excuse me, I'm still puzzled. In said CCTV video, it's patently obvious she is sitting in what appears to be a semblance of calm while he leans and points. It's also pretty obvious she leaps to her feet *after* he grabs her daughter.

It's MOST OBVIOUS there is no soundtrack to this version of events, which PRECEDED the cellphone footage that went viral. So pardon me for asking...how on earth did you deduce she swore at him *before* he grabbed her child?
You will pardon me, but I do a job that requires a pathological attention to pedantry and detail, and I'm still waiting for someone to explain this one to me.
