Finding Missing People
Whenever someone goes missing, especially a child, their case is forwarded to the FBI. If the child is under 12 years old, then the case is escalated and they will initiate an investigation as soon as they know about the cases. They usually monitor from off the ground before getting physically involved.
Looking Into Hate Groups
The idea of hate speech and a hate group is very difficult to define in the eyes of the law. The FBI can only really look into hate groups when threats are being made on a public forum. The Attorney General is able to decide whether or not the group will become aggressive and perform illegal activity. Ultimately, it's up to the FBI to investigate any hate group or speech claims.
