the toothpaste defense
An excuse people on probation use when they report to probation and have to do a breathalyzer and they fail. They say they just brushed their teeth, which leaves small reading of alcohol in their mouth.
Example:
Probation officer: You failed your breathalyzer, you are going to jail.
Probationer: No I didn't drink, I just brushed my teeth before I came here.
Probation officer: don't try the toothpaste defense on me! You're going to jail!
Probation officer: You failed your breathalyzer, you are going to jail.
Probationer: No I didn't drink, I just brushed my teeth before I came here.
Probation officer: don't try the toothpaste defense on me! You're going to jail!
