Q. When one sees Israeli authorities acting in a violent and life threatening manner towards chareidim or any other yiddin, is it permissible to inform the American/Canadian embassy of their actions or any other human rights organization? Is this permissible or is this in the realm of mesira?
A. If there is a possibility of saving people from injury at those demonstrations, Horav Shlomo Miller's Shlit'a opinion is that it is permissible. An accurate feeling of common sense is necessary to avoid creating a Chilul Hashem. As cases are different, and other issues may also apply, a local competent Rov should also be consulted
