The FBI aren't choir boys. They are essentially the domestic secret police of the American Empire. They have a poor record since their founding of violating civil rights, bullying political dissidents and religious and ethnic minorities, and generally using heavy-handed and arguably unconstitutional tactics against their targets as it is-- teaching the agents that not only is it okay to target all members of a particular religious minority, but that they SHOULD is fundamentally dangerous. Any society that values liberty beyond mere lip-service should not be training their law enforcement/domestic intelligence agents in such a way.
If there are any examples or specific cases in which the FBI misused their power against muslims, I'll stand with you against them on those cases. But I can't disagree with the whole strategy which I think is very effective at controlling terrorism.
