SWAT (Sit, Wait, and Talk)

Oldie but goodie from HPD: If you are going to call out a full SWAT assignment and yell out commands for hours and hours on your mega-phone-thingy to an armed and dangerous suspect, holed up inside his home.......MAKE SURE HE IS ACTUALLY THERE!!!!! 16 hour stand off ended when they raided the house, only to find it empty. The suspect didn't slip out un-noticed; he was never there! Whoops.
