Last year a Burqa Lady was shot when she went to the Kotel to daven. When she was asked to reveal her face and identify herself, she kept going towards the Kotel. She either ignored the security guards or did not hear them, but either way they suspected she might be a terrorist and a policeman shot her in the legs after she also ignored a warning shot in the air.

I can't imagine she did not hear a warning shot (and the reports never said she is deaf) - so she must have intentionally ignored the warnings.

It turns out that since then, over the past year she has healed and has also, to the urging of her family, removed her burqa and revealed herself to the world. It seems she was so closed up in her burqa and little world, she lost all sense of communication with those around her. They convinced her of the danger involved, probably not too difficultly considering she was shot in the leg, and she has started to heal in that sense as well.

I guess they found the one successful method of normalizing these women and getting them to remove their burqas. Unfortunately it involves a gun rather than persuasion.
