Hypothetically, how would someone know there was a warrant out for their arrest in another country? That doesn’t seem like public information.
I figure most cyber criminals assume they are untraceable until they get arrested.
In this particular case the person arrested had been very publicly indicted years ago and was most certainly aware.
I got a speeding ticket in Colorado on a business trip and later moved clients and thought to myself “meh I just won’t pay it I won’t be back to Colorado any time soon” and I was stopping entering the country on a trip from the Caribbean for “outstanding warrants”. If I can get stopped for that they should know if they have real criminal charges to not play around.
