California man arrested in Michigan for threatening to attack mosque

Via digby at Hullabaloo, police in Dearborn, Michigan have arrested a man for threatening to attack a mosque.

Roger Stockham, a 63-year-old Army veteran from California who was reportedly angry at the U.S. government, was arrested by police in Michigan and charged with allegedly threatening to blow up a Mosque in Dearborn.

Dearborn police allegedly found Stockham inside his vehicle outside the Islamic Center of America with a load of M-80s in his trunk and other explosives, the Detroit News reported.

Dawud Walid, executive director of the Michigan chapter of the Counsel on American Islamic Relations (CAIR), told the newspaper that police told him the suspect was drinking in a Detroit bar on Monday and threatened to do harm to a mosque in Dearborn. An employee at the bar followed the man outside and wrote down his license plate, which he reported to police, Walid told the newspaper.

One thing I wonder is why exactly this guy threatening to attack a mosque if he was angry with the US government?  Is he mad that the government hasn't expelled all Muslims from the US by now?  Does he think that President Obama is a secret Muslim?  What does the one have to do with the other?
