This video news story reports how police in Rocklin are placing sticky notes on citizens’ personal property as friendly warnings that the property in question may be vulnerable to a crime (e.g., a purse left in a car, a garage door left open, etc.).

The only problem with this police department “courtesy” is that a criminal can also spot the sticky note and, therefore, is alerted by the note of a good opportunity for him to commit the crime that the sticky note is trying to prevent. Duh.
