HONOLULU - The ACLU of Hawaii says it's concerned about the TMT protestors' civil rights. On Friday, it sent letters to local law enforcement with recommendations on "how to fulfill their dual responsibilities to both protect the rights of protesters and maintain public safety."

It says the protests and acts of civil disobedience[that will likely engender a law enforcement response are of concern. It provided tips to law enforcement on how to respond to the demonstrators while still respecting their constitutional rights. Those are:

1) the use of de-escalation and non-escalation,
2) genuine and clear communication with protesters and the public,
3) clear limitations on the use of force,
4) policies against the surveillance of protesters, and
5) adequate and comprehensive training.

This letter offers practical recommendations and guidance from various sources on how best to approach protests and acts of disobedience not only concerning TMT but any future mass demonstrations in Hawaii. 

The ACLU clarifies that it takes no position on the construction of the Thirty Meter Telescope on top of Mauna Kea.
