I disagree, though I do understand that I'm focusing on a different point than you are.
Attempting to leave when told not to just aggravated the situation. I don’t know if use of the Tazer was warranted but if he refused an order to stop three times as reported could be the Ranger felt she had no other option.
Again, there is a time limit beyond which an order to stop is no longer lawful. I don't know what the limit is, but I do know that it is illegal for an officer to detain you indefinitely.
I also know that an officer is legally obligated to respond to the direct questions "Am I being arrested?" or "Am I being detained?". The officer does not have the freedom to not respond to these questions.
I am not certain that the information presented in this thread is complete or fully accurate. However, based on what I've read, it doesn't seem that either side was fully in the right.
Either side doesn’t have to be “fully in the right”. That still doesn’t give the dog walker the right to leave when told to stay.
Giving a police officer a fictitious name is a felony in some jurisdictions. So is refusing to stop when asked to.
