actually these wow women have been getting arrested every month for many years. we didnt do anything new. we ha ve been protesting against them for years. and they have been getting arrested for years. the only new thing is that some judge started allowing them to go there with their tefilin/talis and told the police not to arrest them anymore. hence the curren bruhaha.
btw, rav moshe paskened it is assur and against halacha for them to wear tefilin and even a talis.
