When visiting your country what are things a person must NOT do or be aware of?

No pussy grabbing with the expectation of getting a presidential pardon. Though there is a good possibility if he’s not playing golf that day.

School zones, don’t even drive 1 mph over the posted speed limit, you’ll get a huge fine.

Not murder anyone. That's a no, no.

when driving
getting boxed in by 2 0r 3 hijacker vehicles and forced to stop
community action blocking certain roads /rock throwing
being followed from the airport to be robbed
not all police or traffic vehicles are legitimate law enforcement

Based upon recent events:
Be a person of color, especially speaking a foreign language.
Be identifiable (or even mis-identifiable) as Latino or Middle Eastern. 😒
