Very often the mere fact that you are not trouble makes them pay less attention and the whole thing ends really quickly.
Society needs people to stand up to the police when they exceed their legal remit, or they will continue to exceed it. I won't blame people for choosing personal convenience over the good of society, but we should be clear that that is the choice being made.
I don't like it anymore than you do, I am simply a realist that I can't change the reality of a lot of cops being bullies.
It's a "partial hack" only insofar as it's making them drop their guard and look to finalize the interaction quicker. I've seen these people's faces up close; they are on the edge and any non-cooperation will push them to physically abuse you or even drag you to the station. So I found a way to make them not think of me as a threat, even if two of the times when it happened I had not a minute to waste.
And sadly, when it comes to "people must stand up", it's never us. Always has to be somebody else. Sigh.
Having faced potential costs associated with exercising rights, I must say it can go very bad, very quick.
Done right, even when it does go bad, means a likely win in court.
In my case, preventing warrantless home entry involved:
Personal beating, like ouch! People will notice it happened to you type ouch!
An evening in holding.
Long walk home. (I could have gotten a ride, but was a mess mentally and just walked 10 miles.
A few thousand for a defense attorney.
10 court appearances called for at expensive and tiresome times.
Trial.
Tort to recover fees.
Personal unease for about 6 months while it all played out.
Not recommended.
Unless it is worth it. In my case it was more than standing on principle.
Finally, public defenders are not generally what you want in rights violation type scenarios. Be ready to pay up for experienced representation.
Be ready to take the ride, take the beating, pay the money, lose the time.
I do this too, and will flip the switch in a second if it looks like it will go bad.
One other way to improve ones police interactions is to have one go really bad, then win in court.
Happened to me, and I lack time to tell the tale fully.
Basically, I came home to my family all angry. I sent everyone to their rooms, wife included lol, and stepped onto my porch to have a smoke and think it through.
Sidebar: I really miss that, and am a non smoker today.
Three officers walked up and made demands to enter my home, which I denied and they beat my ass and took me to jail. And it was a non trivial beating.
What they expect is for people to plead down, and I took it to trial and was found not guilty.
Ever since, I have great interactions...
I don't want to open myself up for litigation so I'll definitely put up a fight in this case.
If I am asked to accompany them to the dark room I'll just give up, unlock the laptop, hand it to them and then quietly inform my employer's legal team that a potential security breach has occurred (after I get safely to a hotel).
I really don't want to spend time in jail because of a nervous cop.
1.) Not allow my phone to be unlocked by fingerprint/face.
2.) Not carry USB sticks or similar portable storage devices on my person, to only transport them by courier.
3.) Not unlock my computer for anyone, including the police, unless directed to by our compliance office.
Or it's breach of contract and they can reclaim part of my compensation. I don't work on anything exciting, just Big medical data.
If you're not on their radar, being polite and forgettable is a great way to stay that way.
If you're already in custody, anything you say while being friendly can and will be used against you in court, so your vocabulary should probably be limited to the word "lawyer."
Some situations can be lose-lose. Best you can do is don't talk to the police, and if you absolutely must, say as little as possible and don't lie.
If you're afraid for your safety or they are clearly overstepping their bounds, then complying and fighting it in court is basically the only option (even though it's possible you still get screwed). Otherwise, knowing an asserting your rights can be good, but you have to hope the cop isnt unhinged, dirty, or totally incompetent.
