If a cop is respectful and conducts themselves with a humble mindset, they are more or less trustworthy and worth cooperating with. Otherwise, do not respect any tyrant with a badge. Any cop that comes off as better than you MUST be resisted and put in their place. Yes this may land you in jail. Just goes to show how far our system has fallen. Police cannot arrest you for using your First Amendment against them. Legally they cannot harass you for not cooperating. Cooperation STARTS with the police and ends with us.
Finally, you do not have to say a word to any cop under any circumstance. You have the right to refuse to say anything until your council is present. Obviously your cooperation is your discretion. But ultimately we need to put the SERVE back into PUBLIC SERVANT. And yes... This also goes for our representatives and ALL government officials.
One day your you, next day you're a cop. If you were a decent you then you will be a decent cop. If you a shittybyou, you will be a shifty cop.
Cops are hired straight from the demographics we all inhabit. The choose to "serve". Many forget that is the calling, not to demonstratre authoritarian assholery. Treat everyone's freedom like its your own.
They don't teach that any more. They serve the paycheck and nothing more.
