If I can be shot dead for being pulled over for a broken tail light, or for reaching into a pocket for the driving licence the cop just requested me to produce, or being robbed from all my cash and debit cards without reason, or jailed based on the wrongly conducted roadside "drug" analysis of my donut, yeah, I have every right to be nervous.
Cops are definitely not my friend, I fully expect them to lie, fabricate "evidence" and look for any excuse to cause problems, and it's all on them.
