Oddly enough, you can buy samurai swords on Amazon.

The FBI must prepare its agents for most things.

However, it might have been a first when special agent Jonathan MacDonald and colleagues forced their way into the Palm Coast, Fla., home of Kamil Mezalka, whom they suspected of being involved in child pornography.

For their report claims that Mezalka, standing in his underwear, began stabbing his computer with a samurai sword.

I am grateful to The Smoking Gun for making my Friday more complete by relating this detail.

MacDonald's affidavit presents a moving description of the proceedings.

He says the FBI executed a "mechanical breach of the door" in order to achieve entry into Mezalka's house. Mezalka allegedly appeared from an upstairs bedroom, but was not keen to follow the FBI's orders, instead returning to his lair.

The FBI then, according to MacDonald, entered Mezalka's bedroom, where "I, and my fellow law enforcement officers, observed Mezalka standing in his underwear, holding a two-handed samurai sword, which he had stabbed into the side of a desktop computer."

Some might regard this as a slightly incriminating way to react. So the agents allegedly restrained him to "eliminate any potential danger." To the computer, presumably.

Mezalka stands accused of having a file-sharing program and, using the handle "Wolfcarven," downloading thousands of images of child pornography.

The computer survived the alleged stabbing and provided the FBI with the evidence the bureau believes it needs to proceed with the case.

It seems that, just with a brief perusal of CNET's forums, there are many methods recommended by those who have thought about destroying their hard drives.

Some appear to favor a grinder, others a metal saw, a sledgehammer, a two-foot-diameter degaussing coil, a demagnetizer, or a plasma torch.

I could find no one who recommended a samurai sword.
