Comment: No,they do not advocate violence against police officers except in the fever swamps of right wing media. Please provide a link to support your accusation that BLM protesters chanted that they want "dead cops." The second chant "fry 'em like bacon" was not a call for violence against police but rather a call for equal justice, i.e. if one citizen shot and killed another unarmed citizen in the way that some police have shot and killed unarmed POC, they would face the death penalty. Not to mention that this was one local BLM group.  

BLM is clear about what they want, only those who deny systemic racial injustice view them as a threat. Considering that your posts have demonstrated that you are one of these people, I can see how their movement threatens your confirmation bias.
