Mr. Chiu holds fast to his belief that the police “owe” him an apology and “must” compensate him. Does this happen? Explain.. Offset can be cancelled by sampling it on a capacitor.

Show how to choose concurrent, active comparators from the same source population (or justify the use of no-treatment comparisons/ historical comparators/different data sources).
