State investigators have issued a bulletin warning that members of the Bandidos motorcycle gang may be plotting attacks on law enforcement, and law officers in Waco say it's being treated as a serious threat. Jewelry, a whip and a Bandidos business card are among the items found after warrants were issued to search the belongings of motorcycle club members arrested after a deadly shooting in Waco, Texas. The clothing, patches and other emblems yielded from 41 search warrants reflect the names of at least 10 motorcycle clubs, including the Bandidos and Cossacks gangs blamed for starting the violence Sunday that left nine people dead in Waco. Texas lawmakers have approved motorcycle safety legislation that supporters say was going to be discussed at the biker's meeting in Waco where a deadly shootout erupted.
