Plot hole: It was said that Paddington was caught red-handed robbing Gruber's store however there is no evidence to prove this and most of all the stolen item; the pop up book wasn't in Paddington's possession.
Suggested correction: There is evidence to make people believe he broke in. The evidence that he was in the building confirmed that he "broke in", and Phoenix's testimony that no-one else was there was enough to convict.
