Scottsdale police promised Thursday that other 100 mph speeders photographed on Loop 101 will suffer legal problems. Police last month arrested two Valley residents; city officials have said both were caught by the automated system traveling at 110 mph. Last week cameras have snapped slightly more than 60 motorists speeding 100 mph or faster. 9,798 motorists have been clocked going 76 mph or faster, according to city records received from Redflex Traffic Systems Inc.
