Well, let's make a couple things clear. First, the policeman has no rights - he has only enumerated powers. A minor distinction that has a major impact. Second, the "boy" asserted his constitutional right - if that is "insufficient cooperation" then you are admitting that the 4th Amendment carries no weight.
The bottom line here is the kid was stopped, interrogated and detained for a few minutes and then was allowed to drive off.
Good restatement of the facts of this case. Moving on...
The audible parts of the video document a businesslike respectful police officer. there is really nothing here. Please spend some time in non western non democratic countries before you go off on police authority and constitutional rights.
So if I understand you correctly, you're willing to allow erosion of constitutional rights because it's worse in other countries. That's certainly an odd take, because this country became great by following the standards set in the constitution - not following others. I'm unable to find the section of the constitution that allows searches without probable cause so long as the authorities are respectful, but perhaps I'm missing something.
This incident is petty and really not worth all the consternation being given to it. Its really very similar to the pacifists screaming about 3000 dead in iraq as American Imperialism.
And there comes the slur. At least you were able to avoid invoking Nazism, but I'm sure you must know that these sorts of statements only serve to detract from your overall argument.
BS. The only questions you MUST answer when dealing with the police are those that pertain to your identity. A refusal to answer other questions does not constitute "insufficient cooperation" (whatever that is). Another bootlicker.
