Nothing to see here: Is surveillance during litigation iniquitous conduct or a legitimate investigative practice?
In pop culture at least, solving mysteries has always led investigators to sail close to the wind. A friend and fellow investigator pointed out recently that in one outing Sherlock Holmes stages an accident, lies to witness, is outed as a cocaine addict, daubs himself in fake blood, and tries to steal blackmail material. Modern consulting detectives are more scrupulous, if less likely to be serialised.
