A consent, to be lawful, must be “freely and voluntarily” given. (Bumper v. North Carolina (1969) 391 U.S. 543, 548 [20 L.Ed.2 797, 802].)
Implying Guilt: It is improper to purposely put a subject in the position where he feels that by exercising his right to refuse, he would be incriminating himself or admitting participation in illegal activity. (Crofoot v. Superior Court (1981) 121 Cal.App.3 717, 725.)
Under Arrest: The fact alone that the suspect is under arrest is not enough to demonstrate coercion. (United States v. Watson (1976) 423 U.S. 411 [46 L.Ed.2nd 598]; People v. Llamas (1991) 235 Cal.App.3rd 441, 447.)
Use of Firearms: Attempting to obtain a consent from a suspect while firearms are being displayed will inevitably result in a finding that the consent was coerced. (People v. McKelvy (1972) 23 Cal.App.3rd 1027, 1034: “(N)o matter how politely the officer may have phrased his request for the object, it is apparent that defendant’s compliance was in fact under compulsion of a direct command by the officer. . . . The evidence established ‘no more than acquiescence to a claim of lawful authority.’”)
Even an implied assertion of authority by the police officer may be enough to invalidate a consent to search. (People v. Fields (1979) 95 Cal.App.3rd 582 972, 976; Amos v. United States (1921) 255 U.S. 313, 317 [65 L.Ed.2nd 654, 656].)
Threatening to Obtain a Search Warrant: While telling a suspect that officers will obtain a warrant invalidates a consensual search under circumstances where the officers do not actually have the necessary probable cause to obtain a warrant, threatening to get a warrant when the officers do have the necessary probable cause is lawful. (People v. Robinson (1957) 149 Cal.App.2 282, 286; People v. Goldberg (1984) 161 Cal.App.3rd 170, 188; Bumper v. North Carolina (1968) 391 U.S. 543 [20 L.Ed.2nd 797] United States v. Soriano (9th Cir. 2003) 361 F.3rd 494, 971; People v. Williams (2007) 156 Cal.App.4th 949, 961.)
Threatening to Use a Drug-Sniffing Dog: Threatening to use a drug-sniffing dog, when such use does not require the suspect’s consent and is otherwise lawful, will also not invalidate the
resulting consent to search. (United States v. Todhunter (9th Cir. 2002) 297 F.3rd 886, 891.)
Using a Ruse: A free and voluntary consent, as a general rule, may not be obtained by, or as the product of, a ruse. (People v. Reyes (2000) 83 Cal.App.4th 7, 13; People v. Reeves (1964) 61 Cal.2 268, 273; People v. Miller (1967) 248 Cal.App.2 731.)
Threats to Take Away One’s Children: Threatening to take away one’s children, letting social services take them, if the person does not cooperate, will negate a consent to search. (United States v. Soriano (9th Cir. 2003) 346 F.3 963.) See also Lynum v. Illinois (1963) 372 U.S. 528, 534 [9 L.Ed.2nd 922, 926]; and United States v. Tingle (9th Cir. 1981) 658 F.2nd 1332, 1336; two confession cases where statements were rendered involuntary due to threats to take the children away if the subjects did not cooperate.
Manner of Inquiry: It is not so much what the officer is asking, but rather the “manner or mode” in which it is put to the citizen which determines whether the response is voluntary or not. (People v. Franklin (1987) 192 Cal.App.3rd 938, 941.)
