I want to know how the use of drug sniffing dogs is legal at an immigration checkpoint inside the US border?
EPIC FAIL DUDE.
And we all know what the government is doing here. They are setting up illegal suspicionless drug checkpoints under the guise of immigration check points (WINK WINK). Wake up people please. Stop letting the government get away with violating the constitution and the law.
Secondly United States v. Martinez-Fuerte allowed immigration checkpoints with the scope of determining the immigration status of people going through. Since a drug sniffing dog is unable to determine immigration status having the dog there violates the scope allowed by United States v. Martinez-Fuerte. Again, Having a drug sniffing dog at a checkpoint also violates the law according to the decision that applies to a suspicionless checkpoint which is City of Indianapolis v. Edmond. For those reasons I don't believe that having drug sniffing dogs at an immigration checkpoint is legal.
