BELLEVILLE, Ont. - When asked why he has gone into such minute detail about the crimes committed by Col. Russell Williams, Crown Attorney Lee Burgess said it's all about giving context to how horrific the crimes were.

"I think people really need to know the circumstances of what happened here," he told CTV.ca after court ended on Tuesday.

"You can say someone committed two murders, you can say someone committed two sexual assaults, but it doesn't give you the full context."

Many reporters covering the hearings have wondered why the Crown chose to reveal such great detail about how Williams committed his crimes.

It took two full days to read through the agreed statement of facts about the two murders, two sexual assaults and dozens of break-and-enters and thefts.

Burgess said people simply need to know how monstrous the crimes were.

He also said while Williams is getting an automatic 25 years with no parole, there will likely come a time when a parole board is deciding his future.

That's when the details of his sex assaults, murders and obsession with little girls' underwear will be important.

"Parole boards look at the danger someone presents. If in 25 years they're looking at the danger (Williams) presents, they're going to look back at the record from today," he said.
