Criminals dream up some of the daftest excuses for their actions, mostly because they always know somebody (coughjackthompsoncough) will be stupid enough to believe them. This has to be one of the more absurd reasons of recent memory, however, as a man who stole a PS3 at gunpoint claimed he needed it to rescue his family.
Just near St. Louis, a man was picking out a game in an EB Games store when he pulled a small handgun on the clerk and demanded a PlayStation 3. While most armed robbers don't feel the need to justify themselves, this one did, explaining that his family was being held hostage and he needed the PS3 to obtain their freedom.
Once the robbery was complete, the thief then informed the clerk to call the police after he'd left, because his family needed help. I wager, also, that it's more than the family that needs help in this little story.
