Lately I’ve seen many news reports of a U.S. Supreme Court case involving K9 searches.  The particular case I’ve been seeing has to do K9 Franky from the Miami-Dade Police Department and an arrest that was made in December 2006.  Let me start off by saying that I have not read the police report and am not going to speculate on what was done and whether it was legal or not.  What I am going to discuss is the transcript from the latest oral argument before the Supreme Court on October 31, 2012 (Florida v. Joelis Jardines).  It was a long read, and full of the typical interpretations of the law and constitution. 

The basis of the case is this…a MDPD officer, his canine and another officer approached a house to do a knock and talk.  While approaching the house, the canine was doing what dogs do, sniff, this one just happened to be trained for narcotics detection.  The canine picked up a scent and started to bracket, honing in on the source.  The officers where headed to the front door, which is where the canine lead them and sniffed at a crack in the bottom of the door, then sat down indicating the source.  What exactly happened after that isn’t explained in the transcript.

Let’s break that down a bit.  The officers were at the residence to do a knock and talk.  It had been conceded in Florida court that the officers were lawfully present at the front door.  If I understand it correctly, the defense attorney is trying to say that bringing the narcotics detection canine for the knock and talk was a violation of the defendant’s fourth amendment rights.  During the argument, the Supreme Court cited Kyllo v. United States – 533 U.S. 27, which they read as:

We think that obtaining by sense-enhancing technology any information regarding the interior of the home that could not otherwise have been obtained without physical intrusion into a constitutionally protected area constitutes a search, at least where, as here, the technology in question is not in general public use.” 

In the case of Kyllo, a thermal imaging camera was used to conduct a search.  The defense argued that by using a narcotics detection canine, the police were using “sense-enhancing technology”.  It sounded to me like the Supreme Court was not buying that argument and neither do I.  A canine is not technology, it is using the same sense of smell that we have; just it is much more sensitive than ours.  In comparison, a human has about five or six million olfactory receptors, whereas a dog has about 220 million.  Who hasn’t taken their pet dog out for a walk and it is sniffing at everything.  The only real difference is that a narcotics detection canine is trained to sniff for specific smells and alert us to that smell.  In a way I look at it as an advanced level of obedience, not technology.  We train our canines to heal, sit, down, come, etc, etc, including narcotics detection.  Where is the technology, a veterinarian didn’t surgically enhance the canines sense of smell in any way.  During the bantering, it was argued whether it would be legal for a neighbor and their dog to approach the front door.  Of course it would be, but the defense wanted to try and make an argument of there being a difference between the common house dog and a narcotics detection canine.  Personally, I see a narcotics detection canine as your partner, no different than a human partner.  But that is just my opinion.  Basically the defense was trying to say that the canine was trespassing.  I realize that the defense is trying to get the defendant out of the charges, but in my opinion if the police officers are lawfully present, then their canine would also be lawfully present.
