"One man's trash is another man's treasure."
As a private investigator, I strongly warn you to be careful about what you throw away. In most places trash, once to the curb, can be looked through and taken. Private investigators love looking through trash, and most people have no idea how valuable it can be.
Pay attention to what you're throwing away, and always ask, "Could another person finding this use it against me?" Consider taking your trash to the dump to make it more difficult for people to go through it as well. The person going through it may be a thief, or they could be a private investigator. You see a bag of trash, but they see treasure.
