Writing Homework Help

I’m working on a writing practice test / quiz and need an explanation to help me learn.

1.  What is the relationship between extremists and terrorists? Are they the same, or are they different? Provide examples of extremist groups and terrorist groups to support your response.

2.  Why do law enforcement agencies find it difficult to differentiate what may be a crime of violence or a hate crime from that of an act of terrorism? Provide an example illustrating this dilemma.
