Police in South Carolina engaged in a not-so-hot pursuit as they chased an excavator down a main highway for more than an hour at the speed an average adult walks. Police say the chase reached speeds of 3 mph early Saturday morning with cruisers following with blue lights and sirens in North Charleston after the excavator damaged a building. The very slow speed pursuit went on for an hour and 12 minutes as the big piece of construction equipment with treads and a shovel would not stop. Authorities say the excavator finally got stuck and a drone and police dog chased down the 53-year-old driver, who remains in jail on a $22,000 bond.
