CALGARY - The Alberta Court of Appeal will not impose a tougher sentence on a Calgary computer security expert who was convicted of child porn charges.

Daniel James Clayton was convicted in March of possessing, accessing and distributing child pornography and was sentenced to three years in federal prison.

Some of the computer images showed aggravated sexual assault and violence involving men and babies.

The Crown had sought a five- to six-year jail term and appealed the sentence.

Two of three Appeal Court judges dismissed the challenge, saying that while the trial judge could have imposed a longer sentence, she did not make any legal mistakes.

One justice said Clayton deserved an eight-year sentence and suggested that it is high time that courts do their part to eliminate child porn.
