"What do we want dead cops, when do we want them now!" This chant are others of a similar nature have been heard and recorded at several BLM marches...five Dallas cops were killed at a BLM march, for BLM to then condemn someone for taking this very action they, at the very least failed to control, is hypocritical. For Obama to invite them to the White House was simply him, once again raising his middle finger to law enforcement, and law abiding Americans.
