He also seems to suggest that by rejecting the form, he revoked his consent to search those specific areas listed in the form that were also covered by his general, oral consent. But for the reasons discussed below, his conduct was insufficient to withdraw his consent either generally or in relation to specific areas. Therefore, Davis never limited the scope of his consent. The government relies on case law from the Eighth Circuit for the proposition that “[a] defendant must make an unequivocal act or statement to indicate that consent is being withdrawn.” United States v.
