Courts have long seen K-9 dogs as impartial. Now police bodycams hold them accountable

For decades, American courts have had to take it on faith that drug-sniffing dogs were impartial. Testimony by a dog's handler, along with training records and credentialing by a local K-9 organization, were usually enough. But the recent spread of body cameras now threatens to upend that faith.

A newly filed federal lawsuit in Texas shows cameras' potential to undermine K-9 unit legitimacy. Houston resident Alek Schott accuses Bexar County Sheriff's deputy Joel Babb of pulling him over on Interstate 35 on false pretenses, and then, when he refused to give permission to search his pickup truck, he says K-9 unit deputy Martin A. Molina III prompted his dog to "alert" to the scent of drugs.
