It's contained in the Terms on the Legislature website:
http://www.capitol.hawaii.gov/submittestimony.aspx
It doesn't say "full legal name". Or "first and last legal name". Or "full name as it appears on state issued Identification or other official government identification".
The only named concern is that it is "a real person and not an automated program". No full name is necessary for that, nor would providing what appears to be a full name verify that that is the name of the person submitting the testimony.
This isn't sworn testimony before a grand jury or trial jury under penalty of perjury.
Have you ever gotten a followup email or call after submitting testimony to verify that you are "a real person"? Is anyone here claiming that including an apparent first and last name is "proof" that a person is real and a first name only is "proof" that a person isn't real?
Are you asserting that the 8 people who submitted testimony signed only by what appears to be their first name are not "real persons"? What is the evidence that they are not real persons? What is the evidence that all of the people that submitted testimony with a first and last name
are real persons? Why the hell does it make any difference?
I know, it's their game, their rules, and they can do whatever they want. And obviously do. Doesn't mean I have to like or approve of their irrational diktats (e.g. see "multiburst" being defined using the word "burst" in HB1908, etc.).
