My blog is a bit behind, but I'm back with another exclusive, as reported on Monday and Tuesday.

Wal-Mart has a little problem at its store in Brampton, Ontario. Some bullets that were being stored at one of its stores there, prior to the company getting a license to sell ammunition, are missing.

I first got word of this from a former Wal-Mart plainclothes security employee, someone who works in what's known in the company as "loss prevention".

He'd tipped off his employer that an audit of the ammunition in a storage room didn't add up. His bosses said they would investigate. The employee told me at Global that a few days after his report to Wal-Mart superiors, he was first suspended and then terminated. He says he was canned because the company said he broke a confidentiality rule. (Wal-Mart denies this is why he was fired.) The source, who went on camera for my story on Global, said that as many as 1200 rounds of hand gun and rifle bullets were not accounted for when he hand-counted the inventory.

Whatever the reason for his dismissal, the former employee called police with his information about the bullets. Wal-Mart says it too, filed a report with Peel Regional Police in Brampton, citing the possible missing ammunition.

Wal-Mart now acknowledges that there was a security breach at the store. The company's vice president of corporate affairs, Andrew Pelletier, told me that a hole was discovered leading into the locked room that contained the ammunition. A hole that would have made it possible for someone to enter (and conceivably) to retrieve ammunition that was stored within.

The Peel Police Criminal Investigations Bureau has an investigation ongoing into this case. A source told me that it is possible no one will ever know whether, or how many bullets, went missing from the store. Wal-Mart Canada's Pelletier says that when the company discovered the security breach, it removed the balance of ammunition from the store to another location.

All the while, the company did not have a license to sell ammunition at the store. It was awaiting permission from the federal government, which regulates the sale and storage of ammunition in Canada.

Wal-Mart strenuously explains that it is a good corporate citizen and something like this has never happened before. Some would ask why it happened at all, and why a company (which sells ammunition at about half of its Canadian stores) would be storing ammunition when it did not yet have permission to sell it. This, while the Brampton store was under renovations and a major expansion.

Was this the best environment in which to be storing a stash of firepower?
