During an August 2005 trip however, Dirie and Mohamed talked about whether they should purchase guns for themselves for protection in New York's bad districts. A friend with them insisted he was there for clothing, not weapons, so they dropped him off at a bus stop to travel back to Toronto while they carried on to Ohio in search of a gun. "It wasn't as easy as I thought to buy a gun" Mohamed later said, explaining that they spent two weeks in the United States before they acquired the firearms. However, when they returned to the border to cross back into Canada at the Peace Bridge, border guards found Mohamed carrying a gun in his waistband with ammunition in his sock, while Dirie had two guns taped to his thighs. Although it was believed to be a typical gun smuggling case, the border guards called the Royal Canadian Mounted Police (RCMP), who grew concerned when they noticed the pair were driving a rental car that had been arranged by Fahim Ahmad, who they were monitoring in an anti-terrorism investigation.
