It will be interesting to see what the details really are as they become available.
If he asked her if he was being detained, and she didn't respond, then was he free to go? Did she actually tell him repeatedly not to move? That seems to be in dispute. At first I though that he was just walking away while she was trying to detain him, but it seems like he might have been walking away while she was refusing to acknowledge him. What was really happening? I'm also more than a little confused at how the alleged 'fake name' was 'verified' over the radio. How on earth could the voice on the other end of the radio know that the name he gave was false unless he said he was "Jo Mama" "F. U. Bee-otch"? This definitely sounds like a case of less than half the truth hitting the papers.
On the fake name and no ID issue; this brings up a question that maybe OSR or another police (or maybe an attorney) could clear up. You need to show a license when you are doing an activity that requires a license (driving, carrying a gun in most places, fishing, etc). Walking the dogs doesn't require a license so he didn't really have to have his ID. What would happen if the Ranger asked his name and he declined to give it? If he's not under arrest, why should he identify himself? In fact, since one reason police ask for your name is to see if you have any warrants outstanding, then giving your name may be self-incriminating. Since you can not be compelled to bear witness against yourself, doesn't he have a fifth ammendment right to decline to incriminate himself? In short, why should he have even told her anything? When she told him that the rules had changed, and by the way what's your name; shouldn't he have said "Thanks for informing me of the rules change. I respectfully decline to identify myself. Am I free to go?"
Whatever he should have said or done, it seems aparent that he screwed up at some point. She may well have screwed up herself and I'm holding out to make a solid conclusion untill more info comes out. Still, I'd like to hear a LE perspective on my hypothetical question.
JL - I too am withholding judgement until all the information comes out. Regarding your question about how the fake name was verified, let me just give you an example, using a conversation, I made up, please note, I don't know all CA/Fed. laws, it's just a generalization, based on what
I believe
may have occurred:
Ranger (in uniform) - (notices Hesterberg walking his dog off leash) Sir, your in violation of the new park rules regarding walking dogs off leash.
Hesterberg - I've been walking my dogs off leash here since before you were born, so why don't you do some real police work, and go catch some bank robbers?
Ranger - Sir, may I see some ID please?
H'berg - Why? I didn't break no laws, so I don't have to show you anything.
[meanwhile, fellow dog watchers are gathering, and some are egging H'berg on saying, don't let her take away our rights]
Ranger - I'm requesting to see some ID since your in violation of the new rule.
H'berg - Your going to give me a ticket/citation?
Ranger - I may sir, I haven't decided yet [thinking that she was just going to check his ID, make note of his name in case of a future violation, then give him a warning, and allow him to leave].
H'berg - You know you really a piece of work[actually *@#$] don't you? I don't have ID on me (don't know if this claim is true).
Ranger - That's okay sir, we can verify your ID, if you just give me your name DOB, and residence address. Do you drive or have a valid CA ID on file?
H'berg - It's Jason Stratman. I live at 222 Hesterberg Place, SF,CA. My DOB is XX/XX/XX, and yes I drive, what? don't I look like I know how to drive?
Ranger - Is this correct ? (Reading back info to H'berg.)
H'berg - Yeah!
Ranger - (on radio to her command, gives info to command, who informs her that, there is no Hesterberg Place in the city of SF, no license on file for individual with that name or DOB.
That is how it was figured out, that the name was bogus.
Regarding your other question about not having ID on him. You are correct that no law requires you to have ID on you if you aren't involved in an activity that requires it, but if you commit a violation of the law, and you need to be ID'd, you better have it on you, or you need to be able to prove your ID. See Post #51, and click on the link to a prior discussion for reasons.
Regarding your last question about "What would happen if the Ranger asked his name and he declined to give it?". The answer is it depends. It depends on the officer,
his instincts, and how far he wants to take it. If he wants to take it further, he takes you into custody, and brings you to the station for further investigation. I have released people at this point in the past, and I have taken it further, it also depends on the attitude of the person being stopped,
and most importantly my instincts.
Just my 2 cents, hope this helps you understand.
