The private company that operates speed cameras in Denver, Colorado is ignoring the provisions of state law designed to protect the public. Motorist Bill O'Neil used his cell phone camera to document the lack of warning signs around a photo radar van issuing tickets on First Avenue in January, KMGH-TV reported. City officials entrust Redflex Traffic Systems, an Australian company compensated based on the number of tickets it is able to issue, with the responsibility of placing the signs. A police spokesman told KMGH that signs were out, just on the other side of the road.

Similar tactics are used in the city of Fort Collins, where a speed camera van was hidden behind a bridge abutment on Tuesday. The warning sign was placed on the ground, partially obscured by a planter, the Coloradoan newspaper reported.

In Genoa, Italy a local judge has ruled that average speed cameras are illegal. Justice of the Peace Elena Paolicchi canceled a ticket issued on the A7 between Genoa and Milan after motorists organized by the website strademulte.it challenged the reading of the system known as Tutor. A written ruling has not been issued in the case, but the challenge was filed questioning the system's accuracy and the integrity of the evidence. Red light camera systems known as T-Red caused such a controversy with the shortening of yellow lights and corrupt, backroom deals that Italy's Ministry of Interior last year banned private companies from operating photo enforcement devices.
