NPR- "Why Didn't the FBI and DHS Produce a Threat Report Ahead of the Capital Insurrection?"

Many Trump followers I have spoken with regarding the incident at the capital have expressed that they don't believe the incident was handled any different from the BLM protests over the killing of George Floyd. So many nuances can be argued as subjective, however when we look at the objective facts, the differences are crystal clear. No threat report happens when there is no perceived threat. BLM was a perceived threat and the Trump supporters were not. The question is, why not?
