cops often think they're above the law
Ahh so this is a universal thing, huh? It's similar to what happens in Ghana. Unless police see you dressed and carrying yourself in a way that suggests you're a powerful person, you'll receive all forms harrasment from them on the road.
In regards to cmplxty's specific example of cell data used to accuse people of crimes based on their device location data - this has been used for years by law enforcement Source. You can totally get in trouble if you just happened to be in the same area as a crime.
I'm not sure if my country utilizes this in solving crime, but it sounds like quite an innovative way to pin criminals (aside the abuse it and likely false accusations that might be associated with it too). It doesn't sound accurate or okay to arrest someone just off their pinging their phone in a certain area at a certain time, but if multiple evidences point in the direction of someone, then cell towers can likely help confirm.
