Final answer:
While juvenile justice departments may share information with law enforcement, the extent of this is governed by state laws and may vary. Dillon's Rule limits local government powers and the statement about it providing flexibility is false. The Grant administration did support the Enforcement Acts against Klan violence.
Step-by-step explanation:
The statement regarding the Department of Juvenile Justice releasing information about gang involvement to local law enforcement is a legal question that pertains to specific statutes and regulations which can vary by jurisdiction. Generally, juvenile justice departments do have protocols for sharing certain types of information with law enforcement, especially concerning matters of public safety such as gang involvement. However, the specifics of this can depend on state laws and departmental policies that govern the protection of juvenile information while also balancing the need for law enforcement to maintain public safety and to prevent crimes.
Dillon's Rule is a legal doctrine that relates to the authority of local governments. The rule actually limits the powers of local government to those expressly granted by state law, or those powers closely linked to the expressed powers. Therefore, the statement that Dillon's Rule gives local governments the freedom and flexibility to make decisions for themselves is False.
As for the historical aspect surrounding the Grant administration, it is True that during his presidency, the Enforcement Acts were supported to address violence against black voters by groups such as the Klu Klux Klan. This was a part of the Reconstruction era efforts to protect the civil rights of newly freed African Americans in the South.
