I'm not a drug dealer, but I did get not so nice treatment from police once. Well, more than once but this was the most applicable to this discussion.

I was profiled, verbally assaulted, shouted down, searched, etc. All while AK assault rifles were being waived around to scare me while my car was searched.

I knew I did nothing wrong and it was just corruption and intimidation and fishing. So I responded with yes sir, no officer, etc. Eventually it blew over.

No idea how it would have went if bystanders started getting involved and causing chaos with proximity to the police.
