Nothing could illustrate the respective credibility of the two sides than comparing these two events.
With the AntifaBLM riots, a police officer was deemed to be a murder because of an unintentional death that occurred during the restraining a criminal and partially because of other medical problems. On the other hand, the Wasthington DC incident saw a citizen, not a terrorist, randomly chosen and then deliberately shot to death by a police officer or guard who took his time drawing a bead on his intended victim.
Not surprisingly, we then get people accusing the victim in the latter case of having deserved death while the people who were responsible for a billion dollars of damage in 30 cities and the deaths of over 20 people last summer are supposed to be seen as peaceful and, of course, justified.
