The crazier terrorist Mom acts the more she garners sympathy for the son. Women are wired “to feel” and many a downright jealous -is it a surprise they would try to out feel each other relative to any given subject.
Men are typically the but of jokes in sitcoms advertising -don’t go there with women, they do the shopping more often then not. Women’s common foibles are never/rarely addressed, it’s not good for business.
There is a women in my office that raised her son in a terrible neighborhood, he’s a big strong kid, and he’e been in a lot of troubled as a juvenile through young adulthood now. When he goes to court she has an act she puts on, she in short she acts like a lunatic, has outbursts, dresses strangely and even wears odd wigs. Some people can turn on ghetto fabulousness like flipping a switch. No joke. It’s all a show to garner sympathy for the son...that is, how can you blame him if his mother is bat crap crazy??? He says “yes sir”, “no sir” -throughout. It works once, even twice, but the law of deminishing returns applies as the arrest record builds.
She also cajoles the police to keep her son off the blotter, reverse tact, there she is the diligent Mom trying to turn around a young man.
Terrorist Mother may be employing a tact that works, don’t discount it outright.
IMO the mother is covering her own involvement...if you go back to the beginning and observe her eyes and body language...how she spoke and what said...you see a woman trying very hard to appear innocent..... This is a woman who has something to hide...just as we see the investigation revealing.
