Police let fugitive go during arrest because of his "unpredictable" and "violent" history

Police pulled over a 33-year-old fugitive wanted for assaulting a traffic guard. But they let him go after he refused to co-operate with the arresting officers, who excused themselves by saying the man has an "unpredictable" and "violent" history.

Can you guess what Matthew Kagle, who cannot be arrested because he frightens police officers, looks like?
