Flipping the bird to a resident (expat to expat)
Hypothetically, if expat 2 flipped off expat 1 in a heated exchange, and expat 1 has submitted an official criminal complaint against expat 2. There is irrefutable video evidence and an independent witness.
What happens next with expat 2 (the party with a loose finger and morals), and how much of a hassle is it for expat 1 (the complainant), i.e. requirement to attend court or otherwise.
Thanks in advance!
