Are there terrorists in Denver?

In less than two weeks the DNC will convene their convention in the Mile High City, Denver Colorado. As the excitement grows, a troubling story broke this week.
At an up-scale hotel, not far from Denver's downtown and less than 10 blocks from the state capitol, a man from Canada was found dead. Beside his body, was one pound of cyanide. He had no passport and was reported to be from another country (possibly in Africa).
The family reports that he was a 29 years old salesman, mentally ill and suffered from diabetes. In normal times, a sad story, but this is 2008 and tens of thousands of people are about to descend on the city for a political convention. It was enough to bring in the FBI and the joint terrorism task force along with the local police.
The story has been downplayed, but questions remain. Is it typical that someone with this particular description stay at a $200+ per night hotel? How could he be dead for six days - isn't there daily maid service for those prices? In Denver's hot Summer weather (90s) I'm sure the odor caught someone's attention along with what was reported to be a noticable smell of almonds (cyanide).
Perhaps he had suicide in mind when he brought in 1lb of cyanide to Denver, but that is a hefty amount of the poison for just one person to ingest.
If anyone on this fine site knows anything about cyanide and its distribution as a crowd poisoning, please reply. The reports also state that it is very easy to get cyanide and is a common pesticide.

Two points of order.

Number one, his name was Saleman Abdirahman Dirie. Which leads to the second point of order. He was unemployed, not a salesman.

An unemployed Canadian of Somali origin managed to pay for at least six nights stay at a $200 a night hotel, travel from Toronto to Denver, and purchase close to a pound of cyanide?

What I have read about Sodium cyanide as a chemical weapon is that when mixed with an acid it will create a toxic gas. With the large quantity that was found in the room with the man, it would create a very large toxic cloud. Within a closed area like the Pepsi Center it could be highly deadly.
