When Kang met with the undercover agents he thought were from the Islamic State group at a home in Honolulu, he pledged allegiance to the group and kissed an Islamic State flag, according to court documents. "Kang's military training, weapons abilities and personal combat skills, coupled with his strong stated desire to kill people in the name of Islamic State, makes him one of the more dangerous criminal defendants to have been charged in this judicial district," prosecutors wrote in a motion asking that be held without bail. Federal prosecutors allege Amer Sinan Alhaggagi "went so far as to meet with undercover agents on multiple occasions to plan a potential terrorist attack," said a court filing unsealed Friday.
