if your family letters are inconsistent, you will lose

The Judge ruled that Mr. B, from Burundi, did not deserve asylum. He was one-half Tutsi, he was beaten and hospitalized twice, [and he had records from the hospital]; his father was imprisoned; his brother was murdered, but still, he lost. How could this happen?

The letters from his family contained details different from what Mr. B said in court:
1] Mr. B said he saw brother and sister at home, before he went to the hospital; but brother and sister said they saw him only at the hospital
2] Mr. B said he was arrested and imprisoned; letter from father talked about other subjects and did not say B was imprisoned.

Yes, the hospital records show that B had burns on his hands. However, why did he have burns? did the bad guys make the burns on account of the political opinion of B? Who knows? maybe the burns came from an accidental cooking event.
