It all comes down to small minded paranoia once again. This is the attitude that is destroying Africa.
Thousands of illegal immigrants cross borders daily without any problems, and some of them then make a living out of sometimes serious crime. A person who makes a mistake gets treated in this fashion.

Never heard a word from them after the initial statement.
