“NO POLICE” sign – here’s an interesting approach that didn’t work. The owner of a store that sells marijuana paraphernalia (and marijuana as it turns out) posted a sign that said that police officers were not allowed entry without a warrant and had his lawyer send a letter to the Chief of Police to the same effect. Of course undercover police officers went in and purchased some marijuana from the store owner. The trial court liked the idea and acquitted the guy. The B.C. Court of Appeal not so much saying the sign did not create a reasonable expectation of privacy that the police breached. Back down to the trial division for another trial.
