DUNEDIN, Fla. (AP) — Sheriff's deputies conducting a child porn raid on a Florida home Wednesday found an arsenal of guns and explosives and a homemade silencer, along with a note promising "bloody revenge." Investigators found the weapons — including an AK-47 assault rifle, a 50-caliber pistol, a baseball bat with nails jutting out and 2,300 rounds of ammunition — in a locked closet in the Dunedin, Florida, home where 24-year-old Randall Drake lived with his parents, said Pinellas County Sheriff Bob Gualtieri. During a news conference on Thursday night, Gaultieri said that even more "troubling" is that investigators found aerial images of two schools and a water treatment plant in nearby Tampa.
