Is it proper for a law enforcement offi cer to deliberately avoid attempting to obtain consent to search from the defendant and instead attempt to obtain consent from someone with equal authority over the defendant’s premises? Does it matter whether the law enforcement offi cer had an op portunity to attempt to obtain consent from the defendant and deliberately failed to take it? What if the defendant was deliberately avoiding the police?
