For the second consecutive day, Black Lives Matter was asking its own members to delete photos and videos from social media. The group appears to be concerned that law enforcement will use those photos and videos to make arrests.
Which, according to the DSM Police Scanner Twitter account, is exactly what is happening. It should be noted, however, that DSM Police Scanner is not affiliated with DMPD.
If arrests are a concern for the group, perhaps it is time to stop breaking the law.
