“I don’t see that the FBI has any business there myself.”...
Truth be known, there are FBI agents all over this country in big and in small towns. There are a few right in the town next to where I live in Wisconsin where there is a major interstate “junction” and a MAJOR drug interchange. I understand that these agents mostly work illegal drugs issues which leads me to believe that is why they were either serving a warrant or doing an arrest. Probably the later since the shooting was <> 2:30 AM.
FBI agents aren’t authorized to execute state or local crimes - only those for US Code violations. Murder of a mother is not a federal crime. The story is not accurate.
I don’t know about these two particular agents but a retired cop friend told me the 100 agents brought to Ferguson for the grand jury results were undoubtably there to watch the local cops. He didn’t have a high regard for them, for the most part. That said, they’re law enforcement and they deserve the benefit of a doubt, as most anyone would agree.
