Nobody likes to be stopped by the police, or searched, or arrested… That’s a fact of life. In my experience the individual is either entirely innocent of any wrongdoing and is the subject of a malicious or mistaken allegation, or is up to no good. The former may feel aggrieved, quite rightly, also embarrassed, scared and indignant. The latter may act-up, kick-off and generally be a pr*ck, usually in an attempt to distract from their naughtiness. The police in the meantime will either dust you off and send you on your way, or lock you up. That is the way of things.
How you deal with the fallout is up to you, I suppose… Innocent of any wrongdoing? Either suck it up and move on, or make a formal complaint (social media rant is a third option, I suppose). Know you’re guilty? You’ll probably go no-comment in interview, maybe feign illness in custody and certainly make a formal complaint of mistreatment.
Police, whilst this is all going on… onto the next pile of ****, or victim in need, or traffic incident, etc. until end of shift. Maybe scratch their head at the twenty crimes they need to investigate, but can’t. Certainly await the next complaint, either genuine or malicious. So the world turns.
