Yes, multiple individuals participating in or embedded within Black Lives Matter (BLM) protests recorded themselves committing acts of property destruction, arson, and violence. These self-recorded videos and livestreams were subsequently used by local and federal law enforcement to identify, arrest, and convict them.
Anyone involved in vandalism should be prosecuted properly whether it is BLM, J6, the pool etc etc.... They are all separate instances and comparing them just resorts to whataboutism. In the Hearn case it's was clear they had no real evidence. They had him on camera and he was not in / near the water long enough among other things. Anyone involved in the phony prosecution should be looked at. For trump to keep up the charade after this "new" evidence along with the fact there was no evidence of gashes after draining the pool is comical. If Trump had just said from the get go that we tried an experimental procedure on the pool and it didn't work out, that would have been the end of it. I don't know if he is trying to create a false narrative for distraction, ego, or if he is really that delusional. He does seems to be getting wilder and more erratic with his remarks in general which doesn't bode well for the final couple years. I just hope he doesn't damage the party where the repubs can't win because I can't imagine the dems putting out a good candidate.
